Total Proofs (50 to 55+) estimated to exist: 552+/-Proof mintage: 710
% of Proof mintage estimated to exist today: 78% of 710 Note: Under the formula given, the survival rate of 78% is
unusually high and is unexplained. Perhaps more were saved in groups or small hoards and have survived to the present day, or it could be that many of the coins in the Proof-54 and 55 range represent resubmissions of the same coins (compare with the date 1888, below), or the answer may be that the original mintage figure is incorrect.
