Technical Breakdown: Physics, Metallurgy & Die Diagnostics
Introduced in 1932 to commemorate the bicentennial of George Washington's birth, the Washington Quarter was designed by sculptor John Flanagan. Due to the Great Depression, no quarters were struck in 1933, making the inaugural 1932-D (436,800 mintage) and 1932-S (408,000 mintage) the permanent key dates to the entire series.

Frequently Asked Questions
Why are the 1932-D and 1932-S Washington Quarters so valuable?
Struck during the depths of the Great Depression, commercial demand was so low that only 436,800 pieces were struck at Denver and 408,000 at San Francisco. Most entered circulation immediately and experienced heavy wear, making uncirculated MS-65 or higher specimens extremely rare.
What is the 1934 Doubled Die Obverse (DDO-001)?
The 1934 DDO-001 is the most famous doubled die in the Washington quarter series. It exhibits dramatic Class I rotational doubling with bold split serifs across the entire motto 'IN GOD WE TRUST' and doubling in Washington's hair curls.
Why were no quarters struck in 1933?
Due to the economic collapse of the Great Depression, banks and commercial trade were inundated with circulating coin inventory, causing the Mint to suspend all quarter dollar production entirely for the year 1933.
Where is the mintmark located on silver Washington Quarters?
On 90% silver quarters struck between 1932 and 1964, the mintmark ('D' for Denver or 'S' for San Francisco) is located on the reverse below the center of the eagle and olive wreath. Coins without a mintmark were struck in Philadelphia.
How can you detect an added mintmark fake on a 1932-D or 1932-S?
Because the 1932 Philadelphia quarter is common (5.4 million struck), counterfeiters frequently solder or emboss a bogus 'D' or 'S' onto a Philadelphia coin. Under 30x magnification, authenticators check for solder pools, tooling lines, and verify that the mintmark matches the exact shape of genuine 1932 punches.
When did the US Mint stop using 90% silver in quarters?
Under the Coinage Act of 1965, the composition of circulating US dimes and quarters was changed from 90% silver to a copper-nickel clad composition (cupronickel outer layers bonded to a pure copper core). 1964 is the final year of circulating silver quarters.
What is the auction record for a Washington Quarter?
The all-time auction record stands at $144,000, realized at Heritage Auctions in January 2021 for a breathtaking PCGS MS-66 specimen of the key date 1932-D.
