2020-P Maryland

Philadelphia's Maryland issue, struck in 434,825 pieces, is the larger of the two 2020 Maryland business strikes by roughly 650 coins, the closest P-D split of the entire 2020 American Innovation slate. The Mint released the rolls and bags on December 14, 2020 at $34.50 per 25-coin roll and $117.50 per 100-coin bag, several months after the proof had already shipped in the four-coin set. Maryland ratified the Constitution on April 28, 1788 as the seventh state, which placed the Hubble design second in the 2020 release order behind Connecticut. The Space Telescope Science Institute on the Johns Hopkins University campus in Baltimore has run Hubble's observation scheduling, data archiving, and grant administration since 1990, which gives Maryland a working claim on the design rather than a ceremonial one.

Joseph Menna, then the Mint's chief engraver, designed and sculpted the reverse himself: Hubble in low orbit above a curved Earth limb against a starfield, with "UNITED STATES OF AMERICA," "THE HUBBLE SPACE TELESCOPE," and "MARYLAND" around the rim. Justin Kunz's Statue of Liberty obverse, with relief modeling by Phebe Hemphill, carries across the entire program. Philadelphia strikes from this period typically show even detail across the telescope's solar arrays and the high-gain antennas, with the curved Earth gradient in the lower field reading cleanly when the planchet was free of roller marks. Coins were distributed in 25-coin rolls and 100-coin bags through numismatic channels, so most surviving pieces carry original Mint surfaces.

In the collecting market, the 2020-P Maryland is common in raw rolls and through the lower Mint State grades, and PCGS, the Professional Coin Grading Service, and NGC, the Numismatic Guaranty Company, certify it routinely into MS67 and MS68. Condition rarity at MS68+ rather than mintage drives whatever price the coin commands above face. Year-set and series-set builders need it to complete 2020. The piece is recommended raw for casual collectors and certified at MS68 or higher for registry buyers; the curved Earth limb on the reverse rewards careful inspection under angled light, since uneven die fill in that area is the most common cosmetic defect on otherwise high-grade coins. Background on the program is covered in the American Innovation Dollar series history.
