Wow! Thanks for the memories.If you came to the block with a bottle cap we would probably under estimate you because that was like a beginners style.I wonder if school chair caps was a Bronx thing ’cause they are the only ones i saw posting it. I used to play on Marion ave. and also Decatur ave in The Bronx during the seventies.We took our mothers can openers to school and took the caps off of the chairs to get a professional’s cap. Small caps were called beenies and large were bullies. Sometimes we used clay instead of wax.If your cap began to roll you’d better yell “no kicksies” or we’d kick it like a soccer ball and more than likely you were guaranteed to lose.I think the drug infested eighties destroyed these games like ringoleavio,slugs,of the curb,stick ball,off the wall,kick the can,…………….you get the idea.
