and I was satisfied with the responses the first time. That being said, I was still quite surprised to see a difference of 22.5 times between the upper values listed in the two guides (my chip looks uncirculated). You have to admit $2 to $45 is a bit puzzling. I have decided to hold onto the chip for the time being, however, so I'm not to concerned about it. Thank you for the response.
