So, I've got these black plastic Casino Chips and I don't know where they came form or what to do with them. Maybe someone on the forum can give me some advice. They are solid black except for the white painted mold of card suits (2 ea. hearts, spades, clubs, and diamonds). A black unbroken ring is located on the inside of the mold. The chips just read "Casino Chips" with no inlay or inserts. Are these gaming chips like you'd find at a party or actual casino chips? Anybody know how I can tell?
