Don’t mean to burst your bubble but I wanted to give you a more informed estimate of your chip. At the time of that estimate, the book notes it as an R10 2-3 known. Since then the quantity has changed quite a bit. I would estimate it to be an R8 rarity. It is not worth $25,000 or even $15,000 sadly. It is in very used condition and all the big collectors already have it in much better condition. Plus there have been a few sold recently privately and in auction format like Heritage. Knowing all this, there are $5 collectors that don’t have this chip. A more informed estimate of its value would be in the neighborhood of $5000-9000. Again just my opinion.
