I was watching this auction. I wasn't interested in ones and twos of various colors, I wanted to get at least a barrel at a time. So I was really only interested in the whites and blues. I asked the seller about overstamps, and he said that the four blacks and thirty of the whites were overstamps (he hadn't noticed, he had to go back and check them). So that left only 28 white and 35 blue that I really wanted, so once the price got over $70 I decided I'd pass on it. Looks like someone did snap them up for $80 after he relisted them when the previous winning bidder backed out.
"I have 50,000 plus chips...time to get organized. Get letting go of multiples or things not in my collecting areas." It'll be interesting to see what else the seller puts up in the coming weeks. Seems like a decent guy. He was friendly and helpful when I messaged him.
