I only collect beercaps and at this moment still from all over the world. However, I consider disposing of the caps from the Eastern Bloc Countries. When I can't read what is on the caps I don't like them ;-) I accept the arising conflict with my first all time favourite cap from Svyturys ;-)
In 2016 I created a beercap table from a wooden cable reel on which I glued over 1000 different beercaps which I then embbeded in resin. When the table was finished, I couldn't stop collecting :-)
My all time favourite caps
1. Svyturys Extra: a golden cap with embossed 'Extra' and black text
2. Heineken Quality: a silver cap with embossed text and star
I use Leuchtturm GRANDE COMPART pages for champagne capsules and beercaps. Beautiful but expensive and fragile system. I put them in white panorama binders from Esselte. Exact 9 pages fit in neatly.
