The slab label is too small for a full description of this fabulous error. At the present time, this is the only known, possible 3 denom, US error coin. The only other known 3 denom example was recently lost in a theft.
This incredible piece shows a state quarter obverse, 50% off center, with a full incuse mirror image brockage of Washington, 50% off center on the reverse.
Prior to the strike by the quarter dies, the planchet was double struck by 2000-P Jefferson nickel dies, BUT, it was flipped over between strikes. In the area unstruck by the quarter dies there are clear images of both Jefferson, and the Memorial, on both sides.
All this is on a copper/zinc cent planchet that has expanded to a size that fills a Sac dollar slab.
The final mystery is that some experts believe Lincoln cent designs are still visible under all these other strikes. That makes this either a full 31c piece, slabbed by ANACS MS 62 RED, struck on a Lincoln cent; -OR- a 30c piece on a Lincoln cent planchet.
Unique in the entire history of the US mint, I acquired this amazing error in 2001 as part of my state quarter error collection and as a companion to my Sacagawea Mule error. Inquiries welcome.
