I visited with my contact there today because I thought they had some chips I could buy that had been turned in. Turns out not much! But I did confirm that once upon a time they had PLAQUES! I was told that I couldn't see them although I believe they have yet to be destroyed along with a whole bunch of other chips from previous editions. The PLAQUES were $500, $1000 and $5000 denoms. I am led to believe everything has been audited, they are in barrels and waiting for destruction. Too bad I don't know where the barrels are!
