John R. Sinnock (Whose Initials JS are at the truncation of the neck) designed this dime of a portrait of Franklin D. Roosevelt. Weight is 2.27gms; composition of outer layers is copper nickel (.750 copper, .250 nickel) bonded to an inner core of pure copper; diamerter is 17.9mm; reeded edge. This is a perfect example of the proof coin graded Proof 70 ultra cameo.
