The 1866 Proof Two Cent Piece has a moderately low mintage of 725 coins struck, of which most have survived. Scarce as of PR66 with brown and red-brown color. Full red pieces are rare as of PR65. Any cameo surfaces are great rarities in all grades. Look for either nice toners or blazing red examples.
