1910 Proof St. Gauden Gold $20 Double Eagle

The 1910 matte proof double eagle was produced in an estimated mintage of 167 coins. Surviving proofs are moderately scarce. The 1910 is one of the more accessible proof Saint-Gaudens double eagles. Certified examples appear at major auctions periodically. The proof surfaces show the design in its most carefully prepared form, with mirrored fields contrasting against frosted devices. Each proof was individually struck at the Philadelphia Mint, using polished dies and multiple slow-speed impressions to achieve full detail. Certification by PCGS or NGC confirms the proof designation and protects against confusion with well-preserved business strikes.
