1874 5C PR67 PCGS. With an estimated production of just 700 specimens, the 1874 is among the smaller-mintage proof issues in the Shield nickel series, and Superb Gems such as this are very rare. Delicate gold patina drapes much of the smooth nickel-gray surfaces with glints of lavender on each side. PR67 is the highest grade awarded by both PCGS and NGC. Mintage 700.
