It's not a coin, it's a bullion piece or "round". Its value is tied to the spot price of silver, currently about $12-$13 per ounce.
Sorry no US 1845 silver eagles, but there are Seated Liberty dollars of 1845.
If you have a Liberty Seated Dime, the "CC" mint mark will be on the reverse [tails] side of the coin at the bottom and can be either inside the wreath or just below it. If you have a Liberty Seated Quarter the "CC" mint mark will be on the reverse [tails] side of the coin at the bottom below the eagle. If you have a Liberty Seated Half Dollar the "CC" mint mark will be on the reverse [tails] side of the coin at the bottom below the eagle. If you have a Lbert Seated Silver Dollar the "CC" mint mark will be on the reverse [tails] side of the coin at the bottom below the eagle. If you have a Silver Trade Dollar the "CC" mint mark will be on the reverse [tails] side of the coin a the bottom just above the "D" in "DOLLAR" If you have a Morgan Silver Dollar the "CC" mint mark will be on the reverse [tails] side of the coin at the bottom below the wreath.
With all Morgan Silver Dollars, the mint mark is located on the reverse side underneath the wreath which is below the Eagle's arrows.
There is no such thing as a "Liberty" coin. Almost all US coins have either a depiction of Liberty or the word Liberty on them. Is this a Walking Liberty Half-Dollar? A Barber Dime? A Morgan Dollar? An Indian-Head Cent? A Seated Liberty half-dime? A gold half-eagle? A Silver Eagle? Etc. Without knowing the denomination, it is impossible to answer your question.

No, but there are "Walking Liberty" American Silver Eagle coins.
No Seated Eagle 1842 half dollars exist, But Liberty Seated halves do. So look at the coin again, and check the back under the eagle for a "O" mintmark. Post new question with more information.
1873 was the last year for Seated Liberty dollars. All 1878 circulation silver dollars were Morgan dollars. The earlier Seated Liberty design showed Miss Liberty seated on what is most likely a rock, facing to her right. She holds a Union Shield in her right hand and a pole with a Liberty Cap is in her left hand. The coin's reverse shows a spread-winged eagle holding arrows and an olive branch, surrounded by the words UNITED STATES OF AMERICA, IN GOD WE TRUST, and the abbreviated denomination ONE DOL.
Chief Engraver Charles E Barber designed a Liberty Head series for dimes, quarters, and half dollars, 1892-1916. Miss Liberty was on one side. The other side of the dime had a wreath, that of the quarter and of the half-dollar an eagle.
Please check the coin again and post new question. The Walking liberty design was first used on half dollars in 1916.A genuine 1836 US silver dollar would have a picture of a seated Miss Liberty on the front and a flying eagle on the back. 1836 is a fairly rare date for Seated Liberty dollars so any such coin should be authenticated by an expert.If your coin really has an 1836 date and a Walking Liberty design it's a badly-made counterfeit.
No Standing Liberty dollars have been made by the US, the only dollar coins struck in 1836 are the Gobrecht dollars which have Liberty Seated on the front and a large flying eagle on the back and they are rare. Look at the coin again and post new question.
Please check again and post a new question. The Walking Liberty design was first used on half dollars minted from 1916 to 1947, and again on silver bullion "eagle" coins starting in 1986. The only US $1 coins minted in 1876 were seated-Liberty trade dollars.
