Frequently Asked Questions
Why is the Oregon Trail Memorial Half Dollar considered a masterpiece of coin design?
The coin was designed by the celebrated husband-and-wife sculptural team of James Earle Fraser (designer of the Buffalo Nickel) and Laura Gardin Fraser (one of America's foremost medallic sculptors). One side depicts a majestic Native American warrior holding a bow against a stylized United States map, while the other side depicts an ox-drawn Conestoga covered wagon heading directly into a blazing Pacific sunset.
Over what years was the Oregon Trail Half Dollar minted?
Unlike most commemoratives struck for a single year, the Oregon Trail half dollar was struck across eight different calendar years between 1926 and 1939: 1926, 1928, 1933, 1934, 1936, 1937, 1938, and 1939. Struck at Philadelphia, Denver, and San Francisco, it became a prime example of the commemorative coin proliferation of the 1930s.
What is the rarest and most valuable date in the Oregon Trail series?
The 1933-D is the key date of the series, with an official mintage of only 5,008 coins struck at the Denver Mint during the depths of the Great Depression. The 1938 and 1939 P-D-S branch mint sets are also scarce, with only about 3,000 to 6,000 pieces struck per mint.
Why did Congress end the production of the Oregon Trail coin in 1939?
Coin collectors and the American Numismatic Association protested that private commemorative commissions (like the Oregon Trail Memorial Association) were abusing their legislative charters by requesting tiny mintages each year with multiple mintmarks just to sell them at inflated prices to collectors. On August 5, 1939, Congress passed legislation permanently banning all ongoing commemorative coin authorizations.
What do the 20 stars on the reverse represent?
Above the Conestoga wagon on the reverse, an arc of five stars represents the original Oregon Country, while on the obverse, a series of stars symbolizes the states carved from the vast western territories.
What are the strike diagnostic points on an Oregon Trail half dollar?
The critical high points that show weakness or wear are the outstretched hand of the Native American warrior, the detailed geometric weave of his hip blanket, the canvas ridges of the covered wagon, and the forward legs of the oxen.
What is the weight, diameter, and silver composition of the coin?
The Oregon Trail Half Dollar adheres to standard US commemorative half dollar specifications: 12.50 grams total weight, 90% silver and 10% copper (0.36169 troy ounces of pure silver), a diameter of 30.6 millimeters, and a reeded edge.
