No, there is no silver in a 1817 US penny.
US pennies have never been made of silver.
There is no such thing as a U.S. silver penny.
There was never a silver Indian Head penny.
No such thing as a 94 silver penny.
The U.S. has never made one cent (penny's) coins from silver. The coin has likely been silver plated. It is not rare or special, it's just a penny.
U.S. pennies have never contained silver. Your penny is probably silver plated for jewelry or other decorations.
Yes the 1970 penny is real silver and is worth keeping or even selling
The US has never made and never will make silver pennies. If a penny was silver it would be worth more than a dime.
All 1967 general circulation British Pennies were made from bronze. If you have a silver Penny, it will be because somebody has plated it. Alternatively, the British Maundy Penny is a very much smaller coin than the traditional Penny and is made from sterling silver.
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 :)
One Cent is the value. The US has never made a silver penny. It may look like silver or have been silver plated but it has no collectible value.
