This coin and the coins mentioned in the alternate wordings don't exist.
President Dwight D. Eisenhower's picture appears on all U.S. dollar coins minted from 1971 to 1978.
Peace dollars were only struck from the end of 1921 until 1935. If your coin is dated 1972 it's an Eisenhower dollar and it's made of copper-nickel, not silver, and is only worth face value.
They stopped making the Peace dollar in 1935.
One dollar.
The 1972-S Proof Eisenhower Dollar has a current retail value of $6.50
Peace dollars were not made in 1833.
The fact that the eagles wings are spread tells me it's a Morgan dollar not a Peace dollar. Value is $16.00-$25.00 depending on condition.
About $3.25.
A 1972 Eisenhower dollar is just a big dollar, only proof & special collector's coins sold from the mint have more than face value.
$27.
The last Peace dollar was issued in 1935 so it can't be a 1942 Peace dollar. Look at the coin again and post new question.
the 1972 Kennedy half dollar is worth 50 cents in circulated condition, or about a dollar in uncirculated condition
The is no 1921S Peace dollar; Peace dollars were not produced in San Francisco ("S" mintmark) in 1921. If your 1921 dollar coin is a Peace dollar, it was produced in Philadelphia and has no mintmark; if it has an "S" mintmark, it is a Morgan dollar produced in San Francisco).
