No circulated bicentennial dollars are rare. If it's a silver proof, it will weigh more than a regular Eisenhower dollar, and it will have the mint mark S.
The coin is an Eisenhower dollar, not a Liberty dollar. Only a proof "S" mintmarked coin would have any silver and that's just 40%. None of the coins issued for circulation contain silver. People call them silver dollars just because of the size. Unless it's a proof coin, just spend it.
This would be the 1972 Silver Eisenhower dollar variety from the San Francisco Mint. In uncirculated condition, it would be worth about $8 and if you have a Proof coin, it would be worth about $9.30.
Unless it is part of a mint set, it is only worth $1, it contains no silver (unless it is part of a mint/proof set and the packaging calls it a silver dollar in which case it would be 40% silver) and is a common date.
31,170 for circulation and 470 proof coins. These would be the seated liberty design.
A silver Eisenhower Dollar from 1974 would have came out of the San Francisco mint and would bear the "S" mintmark on it. Also, this coin was only available to collectors so all coins would either be uncirculated or proof coins. A choice uncirculated MS63 coin would be worth about $8.30 while a proof coin would be worth about $11. Note that the value will fluctuate due to the moving price of silver.
Approximately how much is a 1929 silver dollar
I would pay a dollar for a dollar, after all, it is only a dollar.
The 1976 proof sets sell in the $8 range. The Ike proof dollar by itself would be around $4.
No. The 1797 coin would be 1 to 2 millimeters larger.
1879 would make it a "Morgan" dollar.
There was no US silver dollar minted in 1950. If you mean a half dollar, it would be worth at least its value in silver which as of writing is about $7.70 but it would be worth more in better condition. As with all old coins, cleaning harms the value.
I assume you are referring to a U.S. Eisenhower dollar. If it's a circulation strike (copper-colored edge) it's worth face value only. If it's in its packaging from a mint set or proof set AND the package says "40% silver", it would be worth maybe $3.50 or $4 for its metal content.
