Great link jbuck ..... I never knew that CCF resource existed.

All the historical info New Mismatist needs is contained in the library.
There are several fun facts about this coin ..... and they all are contained in the link jbuck provided ....
This coin was minted in 1925 at the San Francisco mint ..... but the mint mark was left off by mistake. Ooooops.

As part of the publicity to sell the coins the entire mintage of 50,028 coins was loaded into a 12-cylinder DeHavilland and flown from San Francisco to Vancouver ..... with the pilot starting the round trip in Vancouver. It was quite an aeronautical feat for the time ..... a round trip of nearly 11 hours with nearly 1500 pounds of cargo on the return leg.
If that plane had gone down .... well .... no Vancouver Halves for us today.

As to this coin ...... the design in high relief makes its very difficult to find one without traces of wear ..... and they were not well cared for following that plane trip.
To my eye this coins shows signs of friction/rub at the high points ..... the hair of Dr. McLoughlin on the obverse and the thighs of the unnamed soldier on the reverse.
I call it AU-58 ..... although it is possible a
TPG would recognize the nature of the design call it MS-64+.
Great coin ..... Thanks for sharing.
