Variety equivalents:
Judd 1690 = Pollock 1892

Rarity: Rare

Metal content: Nickel

Edge: Plain

Notes:
Struck in Nickel, with a plain edge, Judd 1690 is an exact duplicate of the designs that were adopted for regular use in 1883, except for the 1882 date.  The reverse features lacks the word "CENTS" and gives no indication of the denomination except for the large Roman numeral V.  This omission was to cause problems in 1883 when enterprising individuals gold-plated the new coins and attempted to pass them off as $5 gold pieces.  The con artists were successful often enough to force the addition of the word "CENTS" to the reverse in 1883.

Brilliant with some hints of gold toning, and remarkably well preserved and appealing. Deeply frosted devices seem to rise miles above the reflective fields. Popular with both Pattern collectors and Liberty nickel specialists. We note the delicate fields are better than one would expect for this grade, and this is certainly a premium coin for the grade assigned."
