1786 New Jersey Copper. Maris 12-G, W-4790. Rarity-4. Date Under Plow, No Coulter, Shaggy Mane. Fine Details--Environmental Damage (NGC).Medium brown patina on the reverse and around the obverse periphery yields to deeper charcoal-copper throughout much of the field area on the latter side. Rough, granular and pitted throughout to explain the NGC qualifier, yet retaining bold outline detail to the horse, plow, shield and most of the peripheral letters. The date is weak with only the top of the digits discernible. As the most readily obtainable of the Coulterless varieties of the 1786 New Jersey copper, Maris 12-G is popular among type collectors as well as series specialists.
