I, painfully discovered there appears to be two types of Hard Rock collectors. The first is a chip collector that happens to collect Hard Rock chips. This collector expects the chip to have been touched by humans, kissed the green felt of a gaming table, gathered some dirt and maybe a hint of wear. This is my kind of collector. The second is a Hard Rock Chip/souvenoir collector and the chips must not have been touched by human hands, gotten dirty or have been used in any game. These collectors are what slabbing was made for. I have never had any problems with trading or selling on Ebay until I tried to sell some HR chips that apparently were actually used in gaming. The good news is I refunded their money and so far they haven't dinged my perfect Ebay status. I haven't a clue how to tell that a chip is 100% uncirculated, nor do I care. Now if you have read down this far and want some HR chips that are used (according to the previous buyers), I have $90 face + a Trump HR GO for sale at face of $95 plus $4 S&H and insurance. These are earlier HR chips all different. And no you cannot return them. Maybe instead of taking a razor blade to HR chips to make them scarcer, just put them in play. Email me if interested in the lot.
