Many are raw and not graded. Most that are graded are by graders other than PCGS as I see it. But, I agree that this seller is the doctor on ebay. You really counted 163 by PCGS? That sucks. bob :(
I counted 163 offerings from them this evening. All hideous AT silver eagles. Shame is, all were straight graded by our host. No apparent attempt to differentiate AT/NT. "Wow" is all I've got. :(…
