The US Mint has never made a one cent coin of silver. It may have been plated but it's only worth one cent unless you find someone that wants it.
Around $20.00 for a minor mis struck error.
Mis-stamped can mean alot of things -- from a coin that is slightly off-center, a coin that is missing letters due to a foreign substance in the die, or other common striking errors that are not worth much -- to rare doubled die errors, off-metal errors, and other rarities worth hundreds or thousands of dollars. Without knowing exactly what kind of "mis-stamped" error you have, it would only be blowing air up your skirt to give you an estimated value.
It is probably not mis-stamped. Most likely the number 9 became partly filled in on the die and only a part of the number shows. Sometimes if the number is completely filled in the number does not show at all.
Assuming you have a penny dated after 1982, it's actually made out of zinc -- it's just missing its outer copper layer. It has a retail value of a couple of dollars. If it's dated 1943, you have a standard "wartime" cent struck (btw, not "stamped") in steel to conserve copper for the war effort. Unless the coin is in like-new condition, it'll be worth 50¢ to $1.
Not enough information. Please post a new question with the coin's date and a detailed description of the mis-strike* FWIW #1: Coins are said to be struck or minted. "Printing" refers to paper and ink, like dollar bills FWIW #2: "mis" has only one s. "Miss Strike" sounds like a small-town beauty contest winner.
The value of a mis-stamped coin can vary depending on the extent of the error and the rarity of the specific mis-strike. Some collectors may pay a premium for unusual or particularly striking errors, but it's best to have the coin authenticated by a professional to determine its true market value.
It's difficult to provide an exact value without examining the coin, but a mis-stamped 1982 US nickel could potentially be worth more to a collector due to its rarity. Such coins are often evaluated by their degree of error, condition, and demand among collectors. I recommend consulting a professional coin appraiser or numismatist for an accurate valuation.
There are many many ways that it could have been mis-struck. If the coin is simply stamped off center this is pretty common. Depending on the error it could be worth more. The best thing to do is take it to a collector who can properly examine the coin.
The coin is a penny; Penney is a department store. Without knowing how it was mis-struck it's not possible to assign a value. Please post a new question with a description of the error.
I'm not too sure if you're talking about an actual mis-struck nickel, but many people have been confused about the new nickels, these are NOT half-struck, the face on the front is deliberately only halfway on...if you actually have a mis-struck nickel then I'm sure it'll be worth a good amount but sorry, I can't help with that!
It depends on what you mean by mis-struck. Take it to a dealer or collector, the coin needs to be seen for an assessment.
With out seeing the coin, it sounds like it maybe an off-center strike error. Show it to a dealer or collector to find out what it is. As to value? Don't expect to retire.
