My bottle cap collection

In the 1950's Coke had contest to collect bottle caps and save them on the poster, I believe 90 countries / cities were collectable. We used to go by the general store and empty the bottle cap holder from the front of the drink machine into boxes. Then go home and peal out the cork from the bottle cap and see what country we had. Wanted to see if others saved their collections and can flash back to the good old days of the 1950's and being a kid. Thanks
