1875 T$1 Trade Dollar, Judd-1430, Pollock-1573, High R.7, PR66 Red and Brown NGC
Both obverse and reverse are the same as the regular-issue Trade dollar of 1875, but these are struck in copper with a reeded edge. The Judd 10th edition lists the pieces are die trials, but USPatterns.com notes "it is likely that this was deliberately struck for sale to collectors as part of complete off-metal sets. These were struck with the type I reverse with the berry under the eagle's left talon." Aluminum examples are also known of the issue (Judd-1431), both listed as R.8.
