all the breweries in the United States. I advised them that I was making a display of beer bottle caps, for a high school project, and that I would appreciate it if they would send me a single cap from each of the beers that they made.

I received about 400 different beer caps in 1954. Got an "A" for my display and put the 400 caps in a box for the next 50 years.

A few years ago I tried listing them on Ebay one at a time. I was amazed that some of the caps brought as much as $35 for a single bottle cap. Of course they were all mint since they had never been on a bottle.

Bottom line is people collect everything.
