@Pellucidar,
Although not everyone is always in agreement about the Matla prices, the Matla catalog has made the market for years, and not the other way around: comics were and still are traded on the basis of the Matla price. So if you intend to be known to all collectors, please don't underestimate your influence. Then this site will help determine whether the market is growing or collapsing. And believe me or not, many collectors give up when values get fickle and fall. After all, they buy more than a peek-a-boo that can be read piece and then give it with the old paper.
If you constantly maintain an average, it makes no sense to enter the suggested retail price of a new comic: in many cases it is the following week had already fallen anyway. Just check.
I understand your point of view somewhere, but please do not talk about a list price or catalog value anymore. The concept of catalog value is the same for every collector, whether he collects comics or stamps or coins: a guide that absorbs temporary fluctuations and is only adapted to supply and demand over time (often in practice).
The biggest danger lies in the fact that you really only let your “catalog value” depend on the supply.

Just test it for a year and then see how it goes?

I totally agree with Pitske. Perhaps it would be a good idea to replace the word list price with catawiki price. If it does not go well in the test phase, you can replace it with list price and sail a different course. Are you also covered.

The idea is to calculate list prices periodically. Not to do it in real time so that they fluctuate continuously. A period of one year is really too long. See the rise of some of the last Redbeard parts in recent months or the decline of some Tintin facsimiles due to reprints etc.

I don't think anyone can appreciate Pitske's 12-year-old list prices, not collectors, not dealers. It's still a thin string.
Matla has made the market in the past, but unfortunately has not moved with the times, so honest you have to be. No one can ignore the fact that the market is moving and the prices of comics are updated. And yes, sorry, supply and demand always determines the price. In the Matla too, by the way, although it is outdated. This also applies to Peek-a-boo values. In Catawiki they are very up to date, take advantage of them.

Jantje wants to sell his comic books, doesn't know exactly what to ask for and looks at Catawiki. He sees a price there and several people offering the same thing for 90% of that price. So he decides to offer his booklet for 80% of the price. Jantje lucky, he is the cheapest provider and sells his booklet. The result is that the market value will be adjusted downwards, which is an unmistakable incentive for the other providers to lower the price. Pietje wants to sell his comic books, does not know exactly what to ask for and looks at Catawiki ... ........ and so on, and so on
Morits is absolutely right that (many) prices will fall as a result of this principle. What Morits overlooks, however, is that this mechanism requires supply to exceed demand And in that case, prices should fall! that all go back to the banana box unsold in the evening, in my simple view, the price of that book is not good. If I want to buy such a book, it will only be done from a provider who is willing to give me a hefty discount.
The only difference with Catawiki is that in Catawiki the discrepancy between supply and demand can be seen at a glance without having to visit all those market stalls.
Real rare (demand greater than supply) things in good condition just keep on generating money and increasing in value. Thanks to the internet alone, it becomes painfully clear that many things are not as beautiful, rare and sought after as some sellers thought and \ or hoped for.

I am calling for a month to update the value. With the critical point that if the value had fallen too much, compared to the old value, it is then examined how that would have come about.
If it is the Jantje story, then only keep the values of the shop owners / experts.
Malta also cannot keep ALL comics and often prices are already out of date before a new one came / comes. That is not really a starting point, nice, but not really in line with the market anymore.
Catawiki wants to have competitive prices, so doing it like this is the best option. The name "Catalog value" is then idd dubious. But it is also not "Catawiki value". Then more "Market Value".

Sorry, all I mentioned PRICE is value ... MAN shouldn't be typing automatically ...: P

There is much more to Supply and Demand than just retailers. In fact, I suspect that (at most) 25% of the trade is done by retailers and 75% by (semi) private individuals. All actions in buying and selling affect the price and ultimately the value. Since in my opinion value is always behind price, the starting point should be to bring both together as closely as possible.
The real question may well be:
who and what determines a catalog value and how and when is this done. I am very curious about that. I read that an image in which Catawiki plays a major role is always sketched. If that is (again) then you will indeed get large fluctuations, everyone understands that. If you have "global" control, in which you do not just use the Internet as a trading medium, then all major changes in value and price will be absorbed and they will automatically come together.
Perhaps a utopia, but it seems more pleasant to me than an outdated Catalog value. Matla has entered an almost internetless era.
How to continue embroidering on this?

@Rene
things are going in the right direction :-)
However, has you ever contacted an insurance company? Do they not require a "tangible" proof of the value of the estate to be insured? If this changes monthly, they will get a point head to increase / decrease the insured value each time and give up. You would do well to get behind that, I think.

@Pellucidar
So if you go to a comic fair, will all your comics be sold if you put them up for sale at a good price? Never seen that someone did not have to pack anything anymore.
-an automatic price or valuation does not take into account supply and demand: only the current supply is taken into account
-what Willem -Naber writes is perfectly expressed: the price is an indication of the value, but the value does not respond to the issues of the day. An automatic average is therefore not a valuation.
-I am not concerned about the prices of old comics, but of the more recent ones: if the value falls, you get a snowball effect: collectors take off, the supply becomes larger than the market, the prices drop again, etc.
The result will be that again several good series will no longer be published because there is not enough demand and therefore too little is sold to be profitable for the publishers.
I have already experienced this during the “war” between comic shops with increasing discounts.
-The example Kiekeboe: the reaction is downright ridiculous. I just meant that there are buyers who want to read the comics, but do not consider them collectibles: and they will not buy more expensive series or luxury editions. Good, but more expensive series have to rely on collectors, and I wouldn't like to see them disappear. (I mean the good series)
-Also with regard to Matla: of course it is no longer current. This too was only an example of how a catalog has determined the market over the years, and in parallel how big your influence can become. Especially since there is no competition: there is no other recent catalog on the market.
-I am afraid the comment about securing a collection will also be correct and cause problems.
-and I read a comment from a stamp collector: if you want, go for the comics, but let's keep the classic catalog value. For them, mourning is less important because they still have their other catalogs.
-I have been collecting comics for almost 50 years, (and that's before the first Matla catalog is published), Catawiki is a wonderful idea, for and by collectors : if the opinion of several collectors is ridiculed, then I fear that Catawiki will miss its mark.
-And I mean it really well with Catawiki.

Pitske, zie de opmerkingen van René en lees mijn reactie’s aub nog ’s goed. Ik heb, ook gezien je conclusies, weinig behoefte er nog iets aan toe te voegen. Mijn Kiekeboe opmerking was overigens niet bedoeld om je mening belachelijk te maken maar om aan te geven dat Catawiki met de tijd mee gaat en in het gat is gedoken wat achter is gelaten in de markt. Ik heb gezegd: “doe er je voordeel mee”.
En even voor de goede orde, ik geef, zoals altijd, mijn eigen persoonlijke mening op een topic, niet een algemene.
Morits, in verzekeringsland kun je een polis ieder jaar op of afwaarderen. (indexeren) Dat kan toch ieder voor zich doen op 01-01 bijvoorbeeld als het om een verzekerde verzameling gaat. Gezien het open source systeem veranderen de waardes automatisch met de markt mee. Ze gaan mi m.b.t. de verzekerings waarde uit van de winkelprijs en voor 2e hands van de huidige verkoopwaarde in de markt. Zoals René al aan gaf, het item moet terug te kopen zijn in het geval van brand, diefstal of waterschade. Premie zal 1,50 per 1000 euro verzekerd bedrag zijn denk ik.
Ook persoonlijke kwestie voor iedereen.(nieuwstaat, goede staat, redelijk).
Mijn vader en broertje werken bij NN ik zal eens navragen.

Pitske, see René's comments and please read my comments carefully. In view of your conclusions, I have little need to add anything. My Peekaboo comment was not intended to ridicule your opinion, but to indicate that Catawiki is moving with the times and has dived into the gap that has been left behind in the market. I said: "use it to your advantage".
And just for the record, I am, as always, giving my own personal opinion on a topic, not a general one.
Morits, in the insurance world you can up or down a policy every year. (indexing) Everyone can do that for themselves on 01-01, for example if it concerns an insured collection. Given the open source system, the values automatically change with the market. With regard to the insurance value, they assume the retail price and for 2nd hand the current sales value in the market. As René already indicated, the item must be repurchasable in case of fire, theft or water damage. I think the premium will be 1.50 per 1000 euros insured amount.
Also personal issue for everyone. (mint condition, good condition, reasonable).
My father and brother work at NN, I'll check.

Also an additional phenomenon. If you offer items for sale on the site for, say, 90% of the “catalog” value. The value fell by 25% that year. Then the asking price of the article has risen well above the “catalog” price.
As a provider, you have to search throughout Catawiki every month for price differences in order to stay below the “catalog” price. Or do I receive an email from Catawiki with every price change that the price has changed. Or can I, in my pricing, have the option to make my asking price as a% of the list price, so that the asking price of my article falls and rises within certain margin prices.
I am very curious how Catawiki plans to adapt these organizations, without every provider with a reasonable shop constantly working to keep up with his administration.
Can someone answer me?

It's not about how high the premium is, but the insurer will really not believe on your blue eyes that you can pay € 100000 comics. What control do they have that that is indeed the value and not a pile of waste paper? I had to list the books I had (coincidentally already in the computer at the time) and according to Matla's catalog they were able to check that.

How would you like to arrange insurance, by passing on the value of your collection twice a day? In the morning my 25,000 comic books are worth 100,000 euros, in the afternoon 200,000, the next day only 50,000, but fortunately two days later again 175,000 euros.
Such differences are of course not realistic if you have such an extensive (and therefore spread) collection. On an individual level I do see relatively rapid changes in value. Take 32607 The Pirate War (Redbeard). It was offered a few months ago and sold for around 50 euros. Now that everyone can see how in demand it is (searched 19 times) it is sold for 120 to 150 euros. I think it would be useful to include that in the catalog value, because what good would it be if the catalog value were still 50 euros in this case?
bq. Suppose I want to get rid of my stock quickly, I have to offer something to get that speed. So I give a 50% discount. So all items have lost 50% in value? No, of course not.
Of course you are quite right about this. Someone can ask an extreme price (extremely low or high) compared to other providers / realized sales. We therefore leave the extremes out of consideration in the calculation. We've come up with a serious mathematical formula that handles incidents well. This works especially well if there is already a nice supply and a sufficient history of realized sales (we are heading towards the 200,000 strips offered and a lot of them have already been sold, so that is going in the right direction). We will start with it soon.

I would say, take a look, it works, then it works ... if there are real problems, then just as it was again, but then administrators would have to keep the values or an individual case for that.
As I read earlier, it would be nice if an email came with a price change. Preferably every other month or something.

@Morits, Willem is completely correct, just had his father on the phone and he says that an expert from society will come by to estimate and there will be a valuation report. An external valuation from the client is also accepted.
A distinction is made between a private collection and a varying store / dealer stock. For the 1st group, this appraisal is assumed, for the 2nd group the purchase price. The premium is approximately 1.50 per 1000 euros insured value.
What may be useful to know and which also emerged in this discussion, most companies have a fixed term of 5 years for indexation. So + & amp; - in the market (eg Redbeard, Tintin) are excluded during that period.

I don't know much about pricing, but will the following scenario work?
Suppose I want to manipulate the price of an item.
Then I create 30 accounts on Catawiki and put the item in question on the search list for all accounts ...
On my own account I put it in my shop for eg. 300 euros.

Unfortunately you are right Arco. Hopefully “they” will know from now on that administrators “work” at CW? We do our best.

I don't know much about pricing, but will the following scenario work? Suppose I want to manipulate the price of an item.
I will then create 30 accounts on Catawiki and add the relevant item to all accounts on the wish list… On my own account I put it in my shop for eg 300 euros.

We already have ideas for detecting possible fraud.

@Pellucidar.
OK, everyone defends their opinion of course. I sincerely hope that you are right and I am wrong.
