The U.S. did not mint any silver dollars for circulation from 1804 to 1835 inclusive.
In the last few decades there has been a flood of counterfeit dollar coins, mostly from the Far East. Some are excellent and a lot are laughably bad, with impossible designs and dates. If you have an 1823 "dollar" I'm afraid that you have one of the latter counterfeits.
Please look at your coin again. It's likely not a dollar or not from 1823. No U.S. dollars were made in 1823.
If the coin is still in collectible condition, average value is about $60.00.
Please check your coin again. It's either not a dollar, not a Morgan-design dollar, or not from 1823. Morgan dollars were minted from 1878 to 1904 and in 1921. No US silver dollars were made for circulation from 1804 to 1835 inclusive.
1848. Silver. Twenty. Dollar. Coin
There is no such thing as a 1960 silver dollar coin.
One dollar.
The coin is not a silver liberty dollar. It's a 1979 Susan B. Anthony Dollar coin and has no silver in it and the value is one dollar.
1 dollar
As of 2-1-10 value is about $16.50 for the coin.
The coin is face value.
No such coin exists. Silver dollars were last minted for circulation in 1935, and the last silver dollar sized coin was the Eisenhower dollar of 1971-1978, there was no dollar coin minted in 1967.
Look at the coin again the date is 1776-1976 and has no silver in it and is still only a dollar.
