2002-S Ohio Proof

Ohio took the second 2002 slot with a reverse pairing Wright Flyer aviation history against the modern space program, and the San Francisco proof version is where the wing-rib detail and the astronaut's suit creases actually become legible. The reverse depicts the 1903 Wright Flyer skimming above an astronaut figure inside the state outline, captioned "Birthplace of Aviation Pioneers." On a circulation strike the Flyer's biplane struts and wire bracing tend to blur together, and the astronaut's helmet and chest pack lose definition; the proof process pulls each element out cleanly, including the small details on the spacesuit and the lines along the Flyer's wing surfaces. The 2002 Proof Set, which housed this issue, was a ten-coin clad set covering the cent through half dollar plus all five 2002 Statehood quarters, with a reported set mintage of 3,084,245, which is the figure the 2002-S Ohio clad proof carries.

A genuine 2002-S Ohio proof shows the textbook San Francisco signature: deeply mirrored, watery fields with rims squared cleanly from the close-collar press, and the slow double-struck production process pulls full definition out of both the Flyer and the astronaut. By the 2002 run, Cameo (CAM) contrast was effectively standard, with frosted devices reading hard against mirror fields; Deep Cameo (DCAM) is the premium designation and shows on a strong percentage of the issue. Under a 10x loupe, a true proof reveals only faint die-polish lines in the fields, never the radial flow lines that spread outward from a struck-through business strike. The squared, knife-edge rim profile separates a real proof from a prooflike Ohio circulation strike faster than any other diagnostic. Specifications match the standard Washington clad quarter at 5.67 grams, 24.3 mm, cupronickel-clad (91.67% copper, 8.33% nickel) bonded to a pure copper core.

Most collectors pick this coin up inside an intact 2002 Proof Set rather than as a singleton, which keeps entry prices low even at PR69 DCAM. PR70 DCAM commands the only meaningful premium because of how tight the top-pop populations remain. As a high-design-density 2002 Statehood proof, it slots cleanly into a 50-state type set.
