Here are eight metal teacups. Most of them are made of copper. There are three sets of five, two sets of three, one set of two, and two single pieces, for a total of 25 pieces. I couldn't find any stamps on any of them, but one of the single pieces has a stamp like the one in the last photo. I believe they are old, and there is some dirt and deformation. Please refrain from purchasing if you are concerned.
