The 1877 was only minted as a proof with production halted on business strikes. Extremely low mintage of 510 coins (lowest since the 1867 Rays rarity) of which most were saved. Thus, this issue is scarce but very accessible. Scarce in all grades and becoming rare as a high-end gem. Gradually tougher with cameo surfaces and a true rarity with deep cameo surfaces, as only a handful exist.
