It is not a silver dollar, but a silver "art bar" and its value is directly tied to the spot price of silver. Right now that is about $13 an ounce, so expect a dealer to pay about $10 and sell for $15.
The coin you're describing sounds like a generic silver round or medallion rather than an official U.S. Mint Liberty Head silver dollar. Its value would be based on the current market price of silver since it contains one troy ounce of 999 fine silver. You can check the current spot price of silver to determine the approximate value of the coin.
It's a bullion piece sold for its metal value. The current price of silver is around $16/oz.
About $40. It's a bullion piece sold for its silver content. The dollar denomination is artificial. It's also not a Mint issue; the Walking Liberty design is used for one-ounce bullion coins.
It's worth its weight in silver. At present (14 June 2012), silver is worth just under $29 per ounce.
These are both considered common dates for Walking Liberty Half Dollars. In circulated condition, their value will be based mainly on the silver they contain -- currently $2.50 to $3.00 apiece.
Most dates of Walking Liberty halves are common, so the retail value is primarily for the silver content. At current silver prices, one would probably sell for about $6.
half dollars with "Liberty in the name were minted from 1839-1947. be more specific.
The Silver Dollar - 1909 was released on: USA: 15 February 1909
Post new question with the dates.
A Mercury dime is worth about a dollar just for the silver in it. The value goes from there to several thousand dollars for certain dates/mintmarks in high grades.
1922 is one of the most common dates for US silver dollars. They currently sell for around $20-$25 each.
The 1963-D Franklin half is one of the most common dates in the series. It's currently worth about $10.50 for the silver.
Most sell for a couple dollars over the spot price of silver (currently around $18-$20) but a few specific dates have a numismatic premium. There are also proof coins that command a higher price.
It depends greatly on the year, early silver dollar proof dollars can be worth several thousand dollars, modern silver dollar proofs of common dates might be worth $20 or so for silver scrap.
1922 is one of the most common dates for silver dollars. As of November 2012, it's worth around $26.
The Liberty Seated Dollar design replaced it. Historical Note = although all Gobrecht Dollars bear the dates 1836 - 1839, a number of them were in fact minted in the 1850s to the 1870s to satisfy collectors. These, however, still show the original dates of 1836-1839.
