I have traded chips that once were in my collection. Then, I narrowed my focus and no decided I no longer wanted to collect certain types of chips. So, some chips were no longer part of my collection, in my mind. I also just traded a chip that was in my collection at the NE chipper gathering because I had duplicates in there. I had two because both were flawed and I couldn't decide which chip I wanted to keep. I wanted to see Jim G get the chip, so I thought about it for awhile and decided which to keep and which to trade.
