2003-S Illinois Proof

Illinois opened the 2003 Statehood lineup, and the San Francisco proof is where Donna Weaver's young Abraham Lincoln pulls into focus inside the state outline. The reverse sets a beardless, prairie-lawyer Lincoln at center against the state silhouette, with the Chicago skyline rising on one side and a farm scene anchoring the other, framed by twenty-one stars and the inscription "Land of Lincoln." A circulation strike tends to flatten Lincoln's coat lapels, the skyline windows, and the farm-scene plow detail; the proof process pulls each element out cleanly, including the small interior lines on the state outline. The 2003 Proof Set was a ten-coin clad set covering the cent through half dollar plus all five 2003 Statehood quarters, with a reported set mintage of 3,408,516, so the individual 2003-S Illinois clad proof carries that same figure.

A genuine 2003-S Illinois 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 Lincoln's portrait, the Chicago skyline, and the farm vignette. By the 2003 run, Cameo (CAM) contrast was the production baseline, 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 Illinois 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 2003 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 the opening 2003 Statehood proof and the state's bicentennial-era Lincoln tribute, it slots cleanly into a 50-state proof type set.
