Although "Miss Liberty" is seated the coin is not a Liberty Seated dollar (1840-1873), it's a 1877 TRADE DOLLAR (1873-1885) as stated on the reverse. Authentic circulated examples have retail values of $120.00- $350.00. NOTE: The entire series of these coins is known to have replicas, copy's & counterfeits.
No general-circulation silver dollars were minted from 1874 to 1877. If you have a coin that says TRADE DOLLAR on the back, please see the Related Question.
If it's a copy, then it's worth little to nothing. It's made of some base metal, then gold plated.
I have a spoon that has a picture in the center of it which on the back say 1877 is it worth anything

The only silver-dollar sized coins struck in 1877 were Trade Dollars. These coins were made of the same 90% silver alloy as standard silver dollars, but were slightly larger and heavier. They were stuck specifically for use in international trade. A few thousand gold $1coins were also struck in 1877. Their alloy was 90% gold but it included a very small amount of silver and copper for hardness.
Rutherford B. Hayes was the 19th President of the United States, serving from 1877 to 1881. The Hayes dollar coin was minted in 2011, and is worth one dollar.
Those are the years Ulysses S. Grant was President. It's a modern Presidential dollar coin, minted in 2011, and is worth one dollar.
1877 is not a rare date for Seated Liberty dimes. In well-worn condition, it's worth about $10 -- if only very lightly worn, about $20 -- and a nice uncirculated one is worth about $150
