2008-S Oklahoma Proof

Oklahoma opened the final five of the 50 State Quarters program with one of the cleanest reverse compositions in the entire series. Phebe Hemphill sculpted a scissor-tailed flycatcher in flight, wings spread and tail trailing in its signature deeply forked silhouette, gliding above a cluster of Indian blanket wildflowers in the lower foreground. The state name and admission date arc above, the program legend curves below, and the design leaves substantial open field around the bird, a layout choice that punishes weak strikes but rewards the proof format. In Cameo and Deep Cameo execution, the flycatcher's individual primaries and the scissor-tail's deeply forked feathers read as separately frosted elements set against polished black fields, while the petals of the Indian blanket cluster carry a slightly lighter frost that gives the wildflowers visual depth without competing with the bird above them. The scissor-tailed flycatcher was designated Oklahoma's state bird in 1951; the Indian blanket (Gaillardia pulchella) followed as the state wildflower in 1986. Pairing them on a coin reverse was a natural pick that the sculptor executed without overcrowding.

The San Francisco Mint struck 2,078,112 clad proofs of the Oklahoma issue for the 2008 Proof Set and the dedicated 50 State Quarters Proof Set. Authentication of a genuine proof against a prooflike business strike rewards careful inspection. Tilt the coin under angled light: a true proof returns watery, hall-of-mirrors reflectivity across the open fields from polished dies pressing polished planchets under elevated tonnage, while a prooflike circulation piece reveals radial flow lines running outward from the centers. The rims register squared and sharp from the close-collar proof striking, distinct from the rounded shoulders typical of normal production. Under a 10x loupe, die-polish lines run in consistent parallel patterns across the fields, while cleaning hairlines scatter in random directions. Cupronickel-clad construction holds at 5.67 grams and 24.3 millimeters, with the copper core visible as a thin reddish stripe on the edge. PCGS and NGC Cameo and Deep Cameo designations carry significant premiums, particularly where the flycatcher's primary frost remains untouched.
