Mushy Buffalo Nickel Strikes
I've been looking for a while for, among others, the 1926-D buffalo nickel, in a reasonably high grade (for me, for this particular coin, that means AU58-MS63, heavily price sensitive).
The vast majority of these seem to have horrible strikes on both obverse and reverse, often not even showing the horn on the reverse in uncirculated grades. And the price seems to reflect the assigned grade (when buying at this price point, I always buy already graded, and almost always by PCGS or NGC) much more than the detail/appearance (so that a coin that, were it circulated with exactly the same level of detail, would grade at VF30 still is priced at--and, at auction, goes for--around the price guides' MS63 price for an coin graded MS63).
I finally found an MS63 in an acceptable condition (decent, but certainly not excellent strike on both sides).
But this raises a question in my mind: Once a real mushy strike no longer has any luster (fully circulated, below, say, AU55), does its grade drop like a lead balloon, since it had no details to start with? I'm thinking that a mushy copy just a couple of years old could be well down in the low VF range, or worse.
Am I right?
