1911 (S) Lincoln Wheat Cent Die Clash (Reverse — Portrait Through O, N, and C)

Description

This 1911-S Lincoln Wheat Cent exhibits a die clash on the reverse where the back of Lincoln's portrait has been transferred through the O of OF, the N of UNITED, and to the right of the C in CENT — three separate locations where the obverse portrait design created incuse impressions in the reverse die during a planchet-free strike event. The multi-point transfer pattern documents the geometry of the die clash: Lincoln's portrait spans a significant area of the obverse, and when the dies struck each other without an intervening planchet, different portions of the portrait contacted different areas of the reverse die, with the most visible transfers occurring at the O, N, and C positions where the portrait's relief was sufficient to create detectable impressions. This clash is identified as originating from a different die pair than the two obverse-focused die clashes already cataloged for the 1911-S, confirming that at least three separate die pairs experienced clash events during 1911-S Lincoln Cent production at the San Francisco Mint — an indication that clash events were not uncommon in the early years of Lincoln Cent production when press operators were still gaining experience with the new design's die alignment requirements. The Lincoln Wheat Cent was designed by Victor David Brenner (obverse) and struck at the San Francisco Mint in 1911 in bronze composition (95% copper, 5% tin and zinc) weighing 3.11 grams with a 19.05 mm diameter. The 1911-S had a mintage of approximately 4.0 million pieces, relatively low for the series. The reverse-focused nature of this clash — showing the portrait transferred onto the reverse rather than reverse elements onto the obverse — makes it complementary to the two known obverse-focused clashes for the date, collectively documenting clash evidence on both die faces across multiple die pairs from this early San Francisco Mint Lincoln Cent production.
