Have recently come across this and keen to hear any comments from the on line gold bugs if this is a keeper or flip
Well Sir, my take is this coin is rare, for us maybe, so would at least a premium of 100$ be reasonable ! So, to determine this, I suggest an auction run over a week, if you at all can make that effort. However, if you find a buyer, and you're happy, then let that happen.
Not PCGS but NGC auction results: https://www.ngccoin.com/auction-cen.../2011-buffalo-.9999-fine-g50-ms-coinid-710162 The last price realised at auction was spot plus about 12%.
