2008-S Silver Proof

The 2008-S Roosevelt dime proof came out of San Francisco at 763,887 pieces, a 13 percent pullback from the 875,050 2007-S silver figure as silver-proof set subscriptions contracted into the recession year. The 2008 silver proof set carried the silver-content State Quarters and the dime, all using the same 90 percent silver, 10 percent copper alloy that had governed dime composition from 1837 through 1964. The silver dime weighed 2.50 grams against the 2.268-gram clad and carried the S mintmark sharp above the date. Dies were hand-polished to mirror finish on the slower-press protocol identical to the clad-proof workflow, and the silver planchet produced the characteristic white-silver surface tone distinct from the warmer cupronickel hue of the parallel clad proof.

Authentication on a 2008-S silver proof rests primarily on the composition diagnostics. Weight on a calibrated scale must read 2.50 grams against the clad 2.268 grams; this single best non-destructive test reliably separates silver from clad proof issues at the same date. Surface tone should show the bright white-silver appearance characteristic of 90 percent silver rather than the warmer copper-nickel hue of the clad proof, and edge view should display the solid silver-color profile rather than the dark copper-core sandwich visible on the clad. PCGS and NGC encapsulation labels designate the issue as "Silver" and the Cameo and Deep Cameo certifications carry the routine PR69 DCAM and PR70 DCAM premium structure.

The 2008-S silver proof sits in the lower band of the late-2000s silver-proof Roosevelt range, with the 763,887 figure continuing the program's sub-million dip that began with the 2007-S silver proof. PR69 DCAM is available at the standard silver-proof price level and PR70 DCAM forms the meaningful condition-rarity step where PCGS and NGC populations thin to registry-relevant levels. The 2008-S silver proof is required for any modern silver-proof Roosevelt date set and shows no fundamental base-grade scarcity since survival in original packaging remains high. The 2008 silver-proof State Quarters set provides additional packaging-context interest for collectors maintaining intact original holders.
