Thought these 2 auctions were pretty interesting. The one on the top is already at $20.50 with 2 days to go, while the one one the bottom is a BIN at $20/OBO with the same shipping cost. Kinda scratching my head. Why not just BIN for $20 if you're willing to bid that high? The only difference between the two chips looks to be that the one on the top is still casino dirty and the bottom one looks to have been cleaned. Are dirty chips worth more to collectors? Thoughts? I thought the bottom was suppose to drop out on these chips.
