For the most part, antique clay chips with embossed designs are pretty common. This Card Suits, PC-GP, has painted suits and is pretty hard to find. Seymour values as a "g". I have this white version as a dupe. Would like to trade or similar scarce clay poker chips, or will sell for $8, delivered.

These chips are found in red, white, and blue base colors. I haven't seen any other colors.
