Thanks everybody.
In this instance, only have reference photos/descriptions/etc available from the web.
The slab insert REALLY cover the edge of this Buff.
In all of the research that I have completed over the last couple of weeks, there are varying degrees of quality of matte proof strikes. In the case of this coin, I disqualified this coin because of the weak LIBERTY, but, that is not always the case.
A couple more snips to show some square rims next to the obverse and reverse fields.
PS - coin is in transit back to previous owner. Not enough to convince me either. If the edge of the rim could be seen......one can only hope.
