Ron Guth:
In 1805, a real effort was made to produce Quarter Dollars for circulation. The result was a large mintage of over 120,000 pieces, easily eclipsing the tiny mintages of 1796 and 1804. Hundreds of certified, circulated examples complement the many raw pieces that are available to collectors. Mint State examples are a bit more elusive and far more expensive. The most frequently-seen grade is MS63, where at least a dozen examples are known. MS64 examples are rare, and only one example is known in MS65.
Five different obverse and reverse die combinations comprise the whole mintage for this year.
