UNITED STATES: AR 3 cents, 1868, PCGS graded Proof 65, Type 3 silver "trime", a lovely example with light blue reverse toning! Proofs of this date are fairly rare, but not so much as earlier dates before 1866. And proof coins of this date were quite well made and will usually display full strikes, such as on this example.
Estimate: 1,400-1,600 USD
