I was checking the remains of my Sahara, Las Vegas chip collection against my NCV collection and see I have 9 duplicate chips. I believe they are all older tournament chips. A black H&C seems to be hardest to find. I have one, but no extras.
If you need them, or want to start a no-cash-value chip collection, take all 9 for $30 delivered.
If nobody takes the lot of 9, I'd consider breaking out individual chips for half TCR values. Some of these are valued at $20.
