6 troy ounces of silver at $15.90 = $95.40
Actually, it can't exist with only one side, so I assume the reverse is blank. You need to determine why it is one-sided. If it weighs significantly less than a normal dime or shows polishing marks, someone has removed the back of a normal dime and it is not worth anything. But it could be a full-brockage error, meaning something (usually another dime) was between the planched and die when it was struck. These will bring a significant amount, but nothing to plan an early retirement on. You might search eBay to see if any similar errors have been sold recently.
These generally sell in the $5 to $10 range.
The Mint produced 1976-dated Bicentennial Eisenhower dollars for two years (1975-1976) and did not make any 1975-dated dollars. Therefore the mintage for the 1976 coins is very high. In circulated condition, your coin is worth $1.10 to $1.25 -- uncirculated are generally worth $1.50 to $2.00 Another one that's worth a little more if certified MS-65 by a major grading service. Then a coin from Philadelphia lists for $10 and Denver $7. San Francisco minted a copper-nickel proof version that lists for $2 and 40% silver versions that list for $13 in MS-65 and $5 in proof. It's only worth face value.
Answer- updated1945 is considered a common date for Mercury dimes. Look on the back of the coin to see if there's a small mint mark letter next to the E in ONE. It may be blank or there may be a D, S or S. (The W on the front of the coin is the designer's monogram and not a mint mark.)
Numismedia lists the following approximate retail values as of 07/2010:
Circulated coins - about $1.50 to $2 for their silver content. A D or S mint coin with almost no wear might bring $3.
No mint mark (Philadelphia): $5 to $68 depending on quality
"D" mint mark (Denver): $5 to $69
"S" mint mark (San Francisco): $6 to $1,790
There is a variety with a very tiny "S" mint mark called a micro "S". Values are:
Almost no wear - $16
Uncirculated - $26 to $390
