I started to collect my first stay-on-tab when I was 20 years old and treasured more as 1000 from these things, no idea why, probably because I liked metal and they blinked in the sun so much (that must be the crow in me).

Some years later all this ends and I decided to trash this, just to experience some years later, here in Germany exist people who're ready to pay a lot of money for a little amount of this scrap (20 € for 100 pieces), what was really frustrating.
