1865 S Coronet Head Gold $10 Eagle : Inverted 186

What This Coin Looks Like (Obverse, Reverse, Mint Mark Location, Special Features, etc.):

One major variety is the 1865-S $10 Gold Liberty Head Eagle with an 1865 stuck over an inverted 186. This was actually a blunder caused by the original engraver of the coin. A full 3-digit "186" punch was used to save time on engraving - but it was originally struck upside down before the "5" was to be added. Once the mistake was discovered - the engraver struck the "186" right-side up and then added the "5". This resulted in the "8" struck over an inverted "6" - the "6" was stuck over the inverted "8" - and the "5" was stuck over the inverted "1". Only the 865 portion of the date covers the inverted 186. A closeup example image of the 1865 over inverted 186 is depicted below - note the inverted underlying digits identified by the arrows (source of example image is courtesy of Heritage Auction Galleries):
