 Both the Closed 3 and Open 3 varieties are extremely rare, though the official mintage of 25 pieces for 1873 is understated, since more specimens than that are known to exist.In 1875 and 1876, no pieces were struck for circulation, with only pieces in proof condition being made available to collectors.The official mintage is 20 for 1875 and 45 for 1876, though an unknown number of pieces may have been later illicitly restruck for each date.
