I never looked at this as an investment. To date though things may change, as they say never say never you have never see me post a chip for sale. You have not seen me sell a single chip on ebay. Yes, I did divest myself of a few items one in particular and took an offer but short of that have pretty much everything I ever bought.
To me, this is 99.9% hobby if I were looking to invest, chips would not even make my list
