I got these unusual 4 chips from auction. Paid altogether about $10 each. Chips are 6 grams each. Poor description in the auction. Hoped they were ivory or bone, but looks like engraved plastic, faux ivory. No grain at all. Interesting anyway.
Both sides shown: 10, 10, 10 and "V" for five. Anyone have an idea about where they came from.
