I have two PB chips. A one dollar chip and a 5 dollar chip. I had a good story with my 5 dollar chip. I found it in an antique dealers showcase. I asked how much and he said well it's a 5 dollar chips so give me 5 dollars. I was new at the time and had no idea what it was worth, but I knew to give him 5 dollars.

Now it seems like I may have overpaid. LOL
IMO for whatever that is worth I don't see the PB chips going for much over a few dollars each with a few excpetions. There are just way to many out there.
