5/8" with a brass rim and a small hole at top as made. Across the chest area of the images are the names "Lincoln" and "Scott." DeWitt pictures 5 different Lincoln portraits used on 1864 campaign badges but this portrait is not among them. This appears to be an 1860 portrait with the addition of a beard by a re-touching process. The Lincoln side has the tiniest bit of emulsion off just below the drilled hole but above the head area of Lincoln and this tiny loss is essentially invisible unless viewed under magnification. On the Scott side, there are numerous pinpoint dots of loss but widely scattered and again barely even visible unless viewed under magnification. By the start of the Civil War, Scott had already been through 2 wars in service to his country over 50 years. Although a Virginian, he remained loyal to the Union and was one of the few to believe the war would take years rather than months. To defeat the South, he created the "Anaconda Plan" but this was met with ridicule by the Northern press, politicians and younger military officers. In Nov. 1861, Scott retired and passed the command of the Union Army to McClellan. Eventually, Scott saw his plan for victory adopted successfully by President Lincoln and General Grant. Rare and VF. The only example we know of. See post-1896 Lincoln items #170, #211, #587-588.
