It has been a long time since I shared one of these 'comparison' threads ... a brief history and photos that compare the circulated versus MS coins in my classic silver commemorative set.
Topic of this post is the 1937 Battle of Antietam Half Dollar ... designed by Maryland sculptor William Marks Simpson ... he also designed the 1936 Norfolk Half and the 1937 Roanoke Island Half.
This is one of the three coins issued during the series specifically related to the USA civil war ... the other two being the 1925 Stone Mountain Half and the 1936 Gettysburg Half.
Congress approved a mintage of 50,000 coins ... the mintage of 38 assay coins pushed the total mintage of Antietam Half dollars to 50,038 coins.
Alas collectors of the day were in the throes of commemorative burnout given the abuses of the series at the time ... not to mention the continued distribution in 1937 of the Boone, Arkansas, Texas and Oregon Trail Half dollars by their respective agencies.
The Antietam half dollar was issued for an asking price of $1.65 ... unfortunately to collectors of today most went unsold and some 32,000 were returned to the mint for melting.

The net mintage of surviving Antietam half dollars is thus on the order of only 18,000 coins ...
One should readily imagine that such a coin at that time ... purchased by a collector at significant premium ... should remain in MS state ... and such is the challenge of finding these coins in honestly circulated condition!
Today the Antietam half dollar is readily available in most high MS state ...
Truly circulated examples however are nearly impossible to find in the market today ... who would have spent their $1.65 half ... sold only to collectors ... at face value?
Thrilled to share one of each with you ...
1937 Antietam Half Dollar PCGS MS67/CAC
Absolutely stunning coin ... in hand just as it left the mint in 1937.
1937 Antietam Half Dollar PCGS VF35/CAC

Wow ... how did this coin come to be?
Hoping that my 'comparison' threads are of some interest out there ... there are a few other of these posts going back a while.
Enjoy
