1964 Doubled Working Hub Reverse WWHR-001

Description

First cataloged doubled working hub reverse for the landmark 1964 Jefferson Nickel date, attributed by the Wexler Team as Wexler Variety ID: 1964 Working Hub Reverse 1 (WWHR-001). The 1964 date occupies a pivotal position in United States coinage history: it was the final year nickels were struck with individually applied mintmarks and the last pre-shortage production year before the Coinage Act of 1965 fundamentally altered Mint operations. Philadelphia struck an unprecedented 1.02 billion nickels in 1964, and the enormous output required manufacturing working hubs and dies at an accelerated pace — conditions that increase the probability of hub-level doubling when the master die impresses the working hub blank with slight misalignment on a repeated pass. As a WWHR variety, the doubling originated at the working hub stage rather than the working die stage, meaning every die produced from this particular hub would carry identical doubling on the Monticello reverse. This cascading nature distinguishes hub doubling from die doubling and potentially places WWHR-001 coins on specimens struck from multiple different working dies. Three documented WWHRs for 1964 (001, 002, and 003) suggest the hub manufacturing process for this high-demand year may have been pushed beyond normal quality control thresholds to meet production requirements.
