Larry,
My way of thinking tells me it should be worth a whole lot more.
Just how many $500 "Walkers" could possibly be out there.
It's not as if they were a $5.00 chip to keep as a souvenir,
which is why these chips are so rare and are hardly ever seen for sale.
I did a check to see if you had one in your RenoCasinoChips.
I see it's even missing from your site.
That alone must say a lot.
