Postzegels/Elizabeth II Blokje?

Weet iemand details van dit blokje? Of uit welk jaar deze uitgave is?

Deze is helaas doormidden gescheurd, maar ben toch benieuwd.

Does anyone know details about this block? Or what year is this edition from?

Unfortunately this one is torn in half, but I'm still curious.

Further research done: these stamps come from the booklet "A perfect coronation" from 2003.

I now also see that there is another seal of GBP1 in between.
