More information is needed. Are you referring to a dollar coin or bill? Can you describe the image that's on the visible side?
Please post a new question with this added information and we'll try to get you an answer. Thanks!
"COPY" means it is not original. Copies usually have a value equal only to the materials used to make them.
You are talking about an extremely rare occurrence for any coin. I would need to know the type of dollar you have and date to estimate a value - a local coin dealer could give you a ballpark, but with error coins the value is in what a collector will pay. Needless to say if it is a genuine coin, it could have substantial value.
Your 5 dollar bill only printed on one side is worthless. It is counterfeit. It was made by a copy machine.
The reasons of a coin having an image only on one side are varied. I suggest you take the coin to a coin shop and have it appraised to get a more accurate estimate of value.
The value of a quarter with one side stamped heads and the other side blank would be 25 cents in terms of its monetary value in the United States. The design on the coin does not affect its face value or purchasing power. This type of coin may have been altered or misprinted, but as long as it is recognized as legal tender, it can be used for transactions at its full 25-cent value.
50-100 or so
A 1984 nickel with one side stamped with Jefferson and the other side blank is likely a novelty coin created after minting. It does not hold any numismatic value to collectors and is worth face value, which is 5 cents.
The value is just for the silver, about a dollar
Unfortunately regardless of the grade of the coin, the letters stamped on it reduced the value to the silver only, about $3.00
Usually, only 25 cents. Unless it has any odd features like only one side stamped or double stamped ect...
The coin needs to be seen and weighed, take it to a coin dealer. Likely the coin has been altered by some process out side the Mint and is only face value.
??? Roosevelt is on the dime, not the dollar. If you have a large coin (about 38 mm in diameter) with a picture of an eagle landing on the moon on its back side, you have an EISENHOWER dollar. Assuming it's from circulation, it's made of copper-nickel, not silver, and is only worth face value.
