UNITED STATES. Emancipation Bill Passed. Brass Civil War tag (holed, as made). 13.01 gm. 31.4 mm. Bust of George Washington right; UNION below; thirty-four stars around, denticles at the rim / Legend punched in letter-by-letter: GRATE JOY TO OURE RACE around above running from 9 to 3; in six lines down the center: EMAN (the "A" punched in over a mistakenly entered "N") CIPATION | BILL PASSED | APRIL 16 1862 | WASHINGTON | D. C. Musante GW 566. Good Very Fine.

This was created from a Civil War soldier's identification tag (Musante GW-565). The Emancipation Proclamation was signed on the first of January 1863 but Emancipation in Washington D.C. came eight-and-a-half months earlier as celebrated on this piece.
The Musante examples have individual names as the legend around the top half. Those names may have been names of the original owners of the medals, freed slaves. The sale of the Baker Collection in Nov. 2019 offered a named piece noting that the cataloguer was aware of 12 named examples. (That piece sold for $14,400)
