David Hall: The 1939 Oregons were the last of the Oregon series, which ran from 1926 thru 1939, the longest U.S. silver commemorative series. At $7.50 per set, the 1939 Oregons had the highest issue price of any of the Oregons. They also had the lowest mintage, 3004 coins for each of the 1939 and 1939-D and 3005 coins for the 1939-S.
All three 1939 Oregons are relatively easy to obtain in Gem condition. The average grade is MS64 to MS66, with numerous MS63s and MS67s existing. Circulated examples are for all practical purposes non-exsistent. The typical 1939 Oregon is well-struck and mark-free. Luster is more satiny than frosty.
