1875 $10 Sailor Head Ten Dollar, Judd-1444, Pollock-1588, R.6, PR65 Red and Brown NGC
Another example of the Barber Sailor Head motif, here with 13 stars at the rim. The reverse features an eagle like the one that debuted on the 1875 twenty cent pieces for regular issue. TEN DOLLARS is at the lower rim (not FIVE DOLLARS, as stated in the Judd ninth edition), with UNITED STATES OF AMERICA above and IN GOD WE TRUST on a ribbon below the eagle. Struck in copper with a reeded edge.
From the Pollock reference: "Don Taxay cites the Haseltine sale of March 1876 where it is reported that only five examples were struck. The number of auction appearances of the variety, however, suggests that the actual population is considerably larger. Mark Van Winkle reports that these pieces were distributed by the Mint in sets together with examples of [Judd-1439, Pollock-1582]." More recently, USPatterns.com opines that "over a dozen" pieces are known, several of them gilted.
