1859-S near F detail but the coin has a plugged hole (2mm) right above Liberty's head. This is a super-scarce date however, so inspection may be warranted. The San Francisco quarters saw extensive use for decades after being minted making higher-grade survivors rare. In the 5th edition of Mega Red, expert Larry Briggs posits that many 1859-S quarters possess an "etching" on their surface (this coin has that etching), suggesting that they were "unearthed." No further details are provided. (Image)
