No numbers were put on the neck by the U.S. Mint. Take it to a coin collector or dealer to find out what it is.
$1. I'm assuming you mean an Eisenhower dollar with a copper band on the reeding? That is because the Eisenhower dollar was struck in copper-nickel and not silver, as such it is only worth $1.
No US president has been on a SILVER (1794-1935) one dollar coin, but if you mean a large one dollar coin dated from 1971 to 1978 made of copper-nickel, it's Dwight D. Eisenhower.
If you mean a coin? The 1972 dollar coin is an Eisenhower dollar.
Do you mean the circulating dollar coin minted from 1971 to 1978, or the commemorative coin issued in 1990? The circulating coins are worth only a dollar each. The commemoratives are worth about $15.
If you mean a dual dated 1776-1976 Eisenhower Bicentennial Dollar, only the proof and special collector's 40% silver uncirculated coins have more than face values. None of the business strikes are worth more than $1.00
If you mean a real silver dollar, such as a Morgan or peace dollar the thickness is 2.4mm
If you mean the dual-date 1776-1976 dollar it's Eisenhower.
That the people love Dollar's!
Please post a new question that's less ambiguous. If you mean "what's the value of a silver dollar", include its date and mint mark. If you mean "what's the value of a silver certificate", include its date, the letter (if any) next to the date, and denomination. If you mean "how much is a dollar's worth of silver", Google the words SPOT PRICE SILVER and divide 1 by the price in dollars per ounce to get the number of ounces in $1.
If you mean a dual dated 1776-1976 Eisenhower Bicentennial Dollar, only the "S" mintmarked proof and special collector's coins are 40% silver. None of the business strikes are worth more than $1.00. They do have retail values of $1.10-$3.00 depending on the grades but no dealer will buy most of them for more than a dollarThe Melt Value of a 40% silver Ike dollar is $10.00 with silver at $32.20 per ounce.
If you mean a United States silver dollar none were produced until 1794.
5-5-11>> If you mean a real silver dollar made in 1935 or BEFORE, as of today they are worth $29.00 just for the silver.
