Many thanks to Dearborn, 1960NYGiants and fourmack for their responses.much appreciated!
Thanks too, for acquainting me with the Haxby Catalog for 1859 cents. I was not aware of its existence but am sure it will prove a useful tool for attributing the 1859s in the future.
It appears that the Haxby PC59-161 is a solid match and the mystery is solved. The die breaks/cracks are in perfect alignment except for leaf 11 where the crack from the rim to the leaf continuing to the beaded circle is missing from the subject coin. But, I can easily attribute this to the subject coin being in a slightly earlier die state where the crack has not yet had time to manifest itself.
Once again, many thanks for the help!!
