Over the years, as I ran across a chip that appeared to be UNC and was uncommon, I put it in a box. Here are 5 from the box. If you like PQ chips, here's your opportunity for not very much money.

Nevada Palace is not serialized. I believe the Barbary Coast is first or second issue from 30+ years ago. Marina and Bourbon Street are from probably 25 years ago.

Your choice for $4. $2 shipping for any number of chips.
