11cents
The joke answer is 5.5 cents (half of a cent and half of a dime) but if the dime half is actually silver and not copper-nickel would be worth about $2, IF you could separate the pieces.
It's actually a novelty item made by cutting a dime and a penny in half and joining the sides of each. It's very similar to a two-headed or two-tailed magician's coin made using the same techniques.
1963 COPPER penny is worth half a billion dollars.
if the size of your penny is the same size as a copper penny and your penny is SOLID silver then a silver penny would be about 2.1 grams and today(june 25 2012) silver price is about $28.79 an ounce and there are 31.1 grams in 1 ounce making you penny worth about $1.90 but since the (kind of ) rarity it would be about $3 to somebody on ebay(+shipping) hope i helped :)
US pennies have never been made of silver.
The U.S. never minted a silver penny. It would have more than a dime's worth of silver in it. Your coin has been plated.
two dollars
A 1957 cent is all copper. The silver part has been coated with some other metal, so this is a damaged coin with no numismatic value.
U.S. pennies have never been made out of silver. On a 1994-D penny, the silver-colored metal below the copper coating is zinc, NOT silver. It's worth one cent.
A "silver penny" is a steel penny. They were minted in 1943, during World War II, because of the copper shortage. To a collector, it may be worth something, yes, but certainly no amount you could retire on.
A penny.
There is no US silver penny dated 2001. Instead, what has happened is someone has stripped off the copper layer of the coin and left the zinc layer which looks silver-ish.
1963 COPPER penny is worth half a billion dollars.
If it is copper, than it is worth thousands of dollars: unless it is a fraud which you can find out by placing it on a magnet. It will stick if it is fake. If your penny is silver colored, if uncirculated, it is worth about a dollar. if circulated, about 25 cents.
The U.S. never minted a silver penny. It would have more than a dime's worth of silver in it. 1983 and later cents are all made of copper-coated steel so you may have a cent where the copper coating was removed with acid (worth only a penny) or was never plated in the first place (worth a significant amount). It would need to be inspected by a dealer who handles error coins.
U.S. pennies have never contained silver. Your penny is probably silver plated for jewelry or other decorations.
Alchemy is the only way to turn a penny into silver. But post-1982 cents are zinc coated with a thin layer of copper and it is possible to remove it chemically which gives a silvery appearance. However, such a penny is NOT silver, is NOT worth any more than 1 cent.
The 1943 penny was not made with copper, like all other years. Copper was funneled to the War Department so the 1943 penny was made from steel and other compounds.
A 1944 copper misprint wheat penny is worth 1,000,000 dollars.
