From a mintage of 460 coins, the 1864 Proof Three Cent Silver is a much better date for its type. It is more common up through PR63 but gains some scarcity in PR64 and PR65. PR66 and finer are considered rare as there are notable price jumps. Cameo pieces are far more difficult to locate in all grades. Look for attractive toners as this series has many.
