So I started collecting bottle caps in college when I turned 21 with the rule that I had to be the drinker of the brew. 22 years later I’m still collecting and now color coding without purpose or end goal.

Looks like that is a home brew cap of some sort.
Can confirm. It’s been awhile since I’ve brewed but I used these caps when I did.
