1967 Doubled Die Obverse DDO-011

Description

Remarkable for exhibiting quadruple spread — four distinct hub impressions visible on the affected elements — DDO-011 of the 1967 SMS Kennedy Half Dollar stands among the more complex hubbing events in the Kennedy series. Cataloged by VarietyVista as UVC-347 (DMR-022), this variety shows medium quadruple spread on ERTY of LIBERTY and hair detail beneath the R, with lighter spread on TRUST and the 67 of the date. Four superimposed images create a layered complexity exceeding standard doubled or tripled dies. Die stage analysis records Stage B die gouge dots on the T of UNITED on the reverse, while Stage C confirms both obverse and reverse have reached late die state. The SMS designation identifies this as a Special Mint Set issue — the 1965-1967 coins replacing standard proof sets during the composition transition, with a finish intermediate between proof and business strike. SMS Kennedy Halves from 1967 were struck in 40% silver clad, and DDO-011's quadruple spread is best examined on the ERTY letters and adjacent hair detail, where multiple displaced images produce a pronounced visual effect.
