Comic books/Valuation albums33 messages

If I take myself over the years, I see a shift in my (private) purchases. I used to buy a strip with the staple holes; she just wanted to “read”.
I just passed these comics on to the children, over time people become more critical. There has also been a “narrowing” of the collection. Just got rid of series. My purchase policy is now only new comics; do I buy luxury or other more expensive comics, second hand, I want to see them first !!

Often times “buyers” offer you an amount, of which I have something like; then I'd rather make the neighbors happy.
Look at a buyer can safely offer € 0.20 for a strip, which has a value of a multiple …… .. Also understand.

"What is truth?" said Pontius Pilate. With a little paraphrase on this you can ask "what is value?". In economics, that is quite simply the price a buyer is willing to pay for an item.
The best indication for this is realized sales prices.

So it doesn't seem like a bad idea to put the realized sales prices next to the asking prices. I myself am a real estate appraiser and in the housing market buyers and appraisers look directly at the most recent sales prices in a street. These can also be requested online from the land registry for a small fee, even neatly arranged by zip code. There are a lot of appraisers who indiscriminately mention these prices in their “reports”.

There are also many kinds of values; foreclosure value, salvage value, fair value, market value, intrinsic value, fair value, to name a few.
As a specialist in various collecting areas, I have already seen a lot of insane prices on Catawiki. The administrators still have a lot of work to do. Catalog prices are in fact fantasy prices, are an indication. Realized sales prices provide much more guidance.

We should find an algorithm to have the actual selling prices adjust the list prices.
So that will be dynamic pricing, but realistic!
In any case, state the selling prices!

Price suggestions are processed by René (now on vacation).
He is also lagging behind in that respect, patience.

He is back but unfortunately is behind with the price suggestions….

The idea is to eliminate this backlog in one go after some time and immediately afterwards automatically calculate the list prices based on an algorithm in which at least the current list price, the selling price of sold items, the asking prices are important. in shops and the demand for the item (number of times in search list). Extremes are then not included or included. muted so list prices don't rocket like a yo-yo.

Can't the pricing suggestions be communicated to administrators like other changes (without actually implementing them)?
Administrators can then choose whether or not to enter them.

The thing was, most administrators didn't want anything to do with list prices. Incidentally, it is already the case that if an administrator makes a price suggestion himself, it is immediately implemented.

I didn't know that, prices are of course a difficult matter. For the Video Games section, I would not mind if someone made suggestions to me.
Certainly to correct prices that are really completely wrong. That has already happened, but now you have to email and that is quite cumbersome.

Het idee is om die achterstand over enige tijd in een keer weg te werken en meteen daarna de catalogusprijzen automatisch te berekenen op basis van een algoritme waarin in ieder geval van belang zijn de huidige catalogusprijs, de verkoopprijs van verkochte items, de vraagprijzen in shops en de vraag naar het item (aantal keer in zoeklijst). Extremen worden dan niet meegenomen cq. gedempt zodat catalogusprijzen niet als een jojo heen en weer kunnen schieten.

Lijkt me voor die rubrieken waar veel aanbod van eenzelfde item (postzegels / strips) zeer geschikt. Ik heb vandaag meerdere items gekocht in een echte platenwinkel, die bij de Catawiki-verkopers minstens het dubbele kosten in dezelfde staat. Dus met een dergelijk algoritme te hoog worden ingeschaald. Is het daarom niet mogelijk om in het algoritme ook de aanschafprijs van items (die ik nu ook al kan invoeren) mee te nemen, mits aan een aantal voorwaarden wordt voldaan (geen extremen, niet te lang geleden aangeschaft etc.)?

Extremes are then not included cq. muted so list prices don't bounce back and forth like a yo-yo.

Seems to me very suitable for those categories where there is a lot of offer of the same item (stamps / comics). I bought several items from a real record store today, costing at least double that in the same condition from the Catawiki sellers. So being scaled too high with such an algorithm. Is it therefore not possible to include the purchase price of items in the algorithm (which I can now also enter), provided that a number of conditions are met (no extremes, purchased not too long ago, etc.)?

@kdamme, you are right that it will work especially well in sections with a lot of supply. Gradually there will also be more and more supply in other sections than those you mention. I have already thought about including the own purchase price of a collector. The disadvantage is that you will also count the extreme bargains from the flea market and the like (such extremes will not occur so quickly on Catawiki itself). For example, the Doris Dice that is now for sale for 14,000 euros was bought for 1 euro in a second-hand store.
