There is a crest and seal on eBay right now for $320. I believe it’s been at that price for going on 10 years. The chip is $100 chip, if that. When it first appeared on eBay, I believe I offered of $200+ nope it wasn’t enough. A couple have come out since. Good luck with the $320.

Question is why has he not lowered his price. If I had to guess it would be he doesn’t care whether it sells or not.
