LC's description doesn't seem to add up, somehow... "Proof ESC 247 UNC" - is that meant to be two grades, or the strike and then a mention that it wasn't circulated?   The London coins one was definitely a proof, I viewed it. It was ok but had a few marks and cabinet friction on the high pointsAs a buyer/collector, if I chose to buy a proof, by and large it needs to be FDC or very near so. If I was a date or proof collector I may accept less than that if it was scarce or rare. The wear on the reverse of this proof coin (however it came about, 'cabinet friction' is a euphemism for 'wear' to me) renders it totally undesirable to me, each to his or her own I know!
