Judd 1327 is a copper version of the 1873 Trade Dollar. It's purpose is unclear: was it made as an off-metal piece to entice collectors, or was it to test the dies to see how the design would strike up? The other off-metal 1873 Trade Dollar (Judd 1329) was struck in white metal. Both versions are exceedingly rare, though more of the Judd 1329's are known than of the Judd 1327's. Obtaining a Judd 1327 is essentially impossible because the four specimens that are known to exist today are locked up in collections: three in a Wyoming Collection; and one in the Simpson Collection.
