I came from South Brooklyn, and we called it skellzees. In our neighborhood, in the late 60s, we only used bottle caps. Nothing larger was allowed. We weighted them down with melted crayons — in all colors. Some of the houses on our street had slate sidewalks, and they were the best to play on. The bottlecaps would just glide across. Makes me want to play again!!
