"Many 1879-O dollars were released into circulation for a short while and then returned to the Mint and rebagged! Fortunately, this coin escaped the inexplicable actions of the government and was preserved in this pristine grade. Only nine 66s with NONE higher"
A coin that would fit perfectly in a EXTREMELY high grade type set. Wonderful contrast between the prooflike fields and the devices. Not designated on the holder as prooflike. You decide.
