Maris 21-p, W-4920 variety, Curved Beam, Narrow Shield type.  Considered to be Rarity-5.

A less common variety in this looong series, and this is an exceptional example which must rank high in the cc for this issue.

Just a few old lines here and there bear mention, but they are overwhelmed by the absolutely lovely, original chocolate brown color, flashes of 230 year-old mint red in the devices and extraordinary eye appeal of this specimen.

This coin is from the CRO archives and is not currently available for sale.
