Notice anything other than the wear? They both have the Carson City mint marks. The 1977-CC had 1,420,000 minted and the 1876-CC had 1,956,000 minted. Both are over $100 coins, even in this condition. That and the low price I paid were the reasons I know own them.
I collected a small hoard of 1876-CC Lady Libertys raw off eBay on the hunch that they would appreciate over time with the 250th Anniversary of the Declaration of Independence approaching. PCGS XF40 PCGS F15
Here are my 1877-CCs. PCGS XF45 PCGS VF30 - color adjusted to better represent coin. This is a really nice coin except for the "rubber burns."
