Getting them mint might be tough, the ones you have I harvested in the first few days the casino was open. They’re in play at the poker tables, so next time I play I could cherry pick the good ones as they cross my stack. Might be a while before I could accumulate a large numbers of near-mint chips, but we’ll see.
That said, I have at least 7 more mint ones that BSteck didn’t buy that I was going to return to the cage. I’ll put those aside for you if you want.
