In 1870, production of Proof Half Dollars jumped from 600 to 1,000 coins, presumably because of increased collector demand.   Even with the larger mintage, however, the number of survivors of this date is not very much higher than that of the 1869 Half Dollar.  The grade distribution of Proof 1870 Half Dollars mirrors that of 1869, meaning that the most frequently-seen grade is PR64.  Cameo Proof 1870 Half Dollars are very, very rare -- much more so than in previous years.  This makes the odds very small that a Deep Cameo Proof 1870 Half Dollar will ever appear on the market (PCGS has not yet graded one as on 5/2018).
