My nearly 6,000 transactions are combined buying and selling. I'll buy a group, or an entire collection to get one or more chips that I need for my own collection. This means, of course, I end up with many duplicates. These duplicates, and chips I buy directly from casinos, are what I sell on eBay. I don't buy chips for the purpose of resale. But it sure doesn't bother me if anyone else does! Again, I'll be selling starting tomorrow evening.
