I have these cylinders that I have no idea what they could be…They are all about as big around as a half dollar, but they are different heights. One is all turquoise color, and another is part trouquoise. They all have numbers on them, and all have designs on them. Some designs are silver color, and some are look more brass. They seem to be of a composite material. There are over 100 pieces. Would anyone have an idea what they could be? I would like to sell them; if I knew approximately what they were worth. I am downsizing, and really don’t need them..Thanks for any help.
