PCGS 1907-S Barber quarter, struck 3% off-center. Struck slightly off-center, with a portion of the dentils missing. Barber quarters are very scarce struck off-center, with an estimated 15 known. Unique to us as an "S" Mint Barber quarter off-center.
The error occurred when the coin was struck largely out of collar, and also off-center, with some design details missing.
AU53 with mostly white surfaces and a hint of toning. It was dipped at some point (too minor to be noted on holder), but has nice design detail.
