[file] I got these peices in estate….I do not know what they are. They have different thicknesses, designs (that appear to be metal embedded), and even a few that have different colors. they are some type of composite material. They are about the same size as a quarter. I have ask a lot of people what they are..no one seems to know. I would like to know if they are worth anything..how much to ask.. and what to call them. If anyone has any idea I would appreciate hearing from you. Thanks for looking at my listing. Look forward to hearing from you.
