2020 (P) Marsh-Billings-Rockefeller National Historical Park Quarter - Doubled Working Hub Reverse WWHR-001

Description

2020-P VT WWHR-001 is a working hub reverse variety on the 2020-P Marsh-Billings-Rockefeller National Historical Park quarter (Vermont) in the America the Beautiful series, cataloged by the Wexler team. Wexler classes it as a working hub problem caused by hubbed-in debris, not as doubling: the mark is neither a doubled die nor a strike through. On the right side of the tree, between its two lowest branches, sits a sunken (incuse) mark shaped like a branch. Because the problem lay in the working hub, Wexler gives no die markers for either side; they differ from one affected working die to the next. Kenny McClure and George W. Powell, Jr. submitted it. Wexler lists no cross-references. Wexler's comments say the mark looks a lot like the true doubled dies recorded on this design, except that it is sunk into the surface, where real doubling stands raised. The present view is that a clogged master die was to blame, since these coins often lack detail on the lower branch. When a working hub was made from that master die, some of the debris broke loose and was pressed into the hub, leaving the branch-shaped mark on it. Small differences in how the mark looks may come from wear on the hub or on dies made from it, though more than one working hub made from the clogged master die may also have taken in the debris. This hub, or at least one carrying the same debris, also made working dies for the West Point mint. Wexler has found that the earlier listings WDDR-003, WDDR-004 and WDDR-005, along with WDDR-006 and WDDR-007, all come from WWHR-001.

• None known Comments: This appears much like true doubled dies known for this design except that this mark is incuse while true doubling is raised. The current belief is that this was caused by a clogged master die as missing detail on the lower branch is a common issue on these coins. While creating a working hub using this master die, some of this debris became dislodged and was pressed into the working hub, leaving this branch-shaped mark on the hub. Slight variance in the appearance of this mark may be due to wear on the hub or the dies created from it, though it is also possible that multiple working hubs created from the clogged master die were hubbed in this debris. This working hub, or at the least one also hubbed in the same debris, was also used to create working dies for the West Point mint. The following previously listed varieties have all been determined to be from WWHR-001: WDDR-003, WDDR-004, WDDR-005, WDDR-006, and WDDR-007.; Wexler Variety ID: 2020-P 25¢ VT WWHR-001
