While I was in Photography class in high school, we used to go into the dark room and put pennies in the fixing agent trays. The copper would attract the silver that was left behind in the trays due to the developing process. The longer you left the copper in the tray, the more silver would be attracted to it. Works with other metals as well. Hope this helps.
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.
copper
i found a gold penny once. try scratching off the gold, like i did. the color scratched off easily and the result is a normal penny. But i dont know how they make gold pennys, or the reason More Information: A penny can tarnish to a golden hue. The environment it is in can cause it to tarnish different colors. For example, gold color, blue color, black color, shades of red color. A penny could be gold plated but it would destroy its numismatic value.
silver
It means that it is gold electroplated silver. The 925 means purest silver. The piece is not gold, it is silver.
The penny turned silver color due to a process called oxidization. Over time, the copper in the penny reacts with oxygen in the air to form copper oxide, which appears silver in color.
Its zinc
In mint condition it will be silver.
Lincoln cents were struck on zinc coated steel planchets in 1943 only, the color often appears to be silver.
because nick is really cool
No, there is no silver in a 1817 US penny.
US pennies have never been made of silver.
There's no such thing as a silver US penny, only silver-colored ones. If it's silver in color it's most likely plated. However if it feels slippery do not touch it any more and throw it out because someone put mercury on it to change its color. You could get mercury poisoning if handled too frequently. If it's a 1943 cent, and silver in color, it's a common steel wartime cent worth about a quarter in average condition.
It has a silver color because it is made out of steel. Copper was needed for the war and was in short supply, so steel pennies were made.
There is no such thing as a U.S. silver penny.
It's likely to be chrome or nickel plated and is very common but it don't add to the value.
No. The US 1961-D penny is 95% Copper and 5% Zinc. Any "silver" cents you have are almost certainly plated. The only exceptions are the famous 1943 steel cents. These have a silvery color in their original condition.
