This variety is a singleton, and I believe the only overdate in the counterfeit CBH series. All known examples were struck on brass planchets. Currently, about 10 examples have been documented.
 
I love this variety probably because of the overdate. This is the first time I've offered this variety here, and examples rarely surface for sale. This piece has VF details but the brass planchet has not been kind to the surfaces over the past 180+ years and there is surface pitting. This piece is a trade-off between details and surfaces.
