1” (25mm) with portrait of Lincoln and his name on the brass frame reading “Abraham Lincoln 1860.” Reverse depicts and reads “Hannibal Hamlin 1860.” This design is listed as DeWitt/Sullivan AL1860-101. The Lincoln image is gorgeous and the condition of the emulsion is essentially flawless Mint. The Hamlin side is just a trifle darker and the emulsion is almost as nice as the Lincoln side with the exception of a pinpoint raised dot on the upper right edge of his head. This just catches a little reflected light and is as made rather than a defect. Luster on the brass rim is very bright with a little natural shaded patina acquired over the decades. Larger than the typical 7/8” size and truly rare in this outstanding condition.
