You can take it to the bank and get a dollar. If it is a .999 pure silver dollar then do NOT take it to the bank.
The US did not print any two dollar silver certificates after 1899.
Please post a new question with the coin's country. It can't be an American silver dollar because the US didn't mint any silver dollars after 1935. No new $1 coins were issued until 1971. If the coin has a picture of an eagle on the back and the words HALF DOLLAR that's a strong clue that it's not a silver dollar.
The coin is a Franklin half dollar (1948-1963) and is common. If the coin shows any wear, value is about $10.00 just for the silver.
The US did not make any silver coins dated 1978, if the coin is a large size Eisenhower dollar its likely only face value unless its Proof or Uncirculated.
The designation "BU" for any coin means "Bright Uncirculated".
One dollar is the same as any other dollar. As opposed to silver dollars being worth more than paper dollars.
None of the one dollar coins released for circulation after 1935 have any silver. So the 1935 Peace dollar was the last U.S. 90% silver one dollar coin.
None of the Eisenhower dollars made for circulation have any silver in them and are only one dollar.
The US did not print any two dollar silver certificates after 1899.
Silver dollars have .7737oz of silver in each.
Any silver dollar that has a letter or number added to the coin reduces it to the silver value only, about $12.00
You should never polish a silver dollar or any old coin. Any standard silver polish you have at home will damage the coin's surface and reduce its value.
The U.S. didn't mint any silver dollars that year.
The date of any dollar is at the center bottom.
No half dollars intended for circulation minted since 1970 contain any silver. No 1972 half dollar has any silver. It is only worth 50 cents.
No US Dollar coins dated 1823 or any Silver Lady Head coins?
The U.S. did not mint any dollar coins in 1960.
