Hi.. hope I'm in the right subforum Need some guidance I have a 1965 silver looking (bright and shiny) lincoln head penny. How do I go about finding out if its real and possible value ?? Feel free to post questions in laymans terms please as I'm not really a collector Thanks in advance Jim
You didn't really answer any questions or give advice With your 3 years and almost 17,000 posts I appreciate your experienced reply Jim
Are you able to post a picture or a scan of the coin? It is likely plated as that is a very common scenario but a picture would help. Thanks, Bill
If it weighs the same as a normal pre-1982 cent, and is the same size it is most likely produced by this method. It is a very popular chemistry experiment ( in several lab books) for middle or high school. You can make gold or silver colored cents. http://www.metacafe.com/watch/1262456/make_a_gold_penny/ Jim
That is interesting, and what you should get without any pictures, or details. . [that is a period]. Note: The OP was the equivalent of "I found a coin. What is it worth?"
Since your coin weighs more than a silver dime, then it isn't silver. If it was the same size and weight as a dime, then it might be something, since silver dimes dated 1964 were struck well into 1965, and there would be an odd chance that a silver dime planchet (a plain round disk that is minted into a coin) could have gotten mixed into the cent planchet bin.
Most likely it's been heat-treated. The melting point of zinc and tin are lower than copper. When you heat the coin, the zinc and tin will melt and come to the surface of the coin giving it a 'silver' appearance. I've done this to a couple 60's cents and it's pretty cool. All you have to do is toss it onto a hot range top for a few seconds and then let it cool. VIOLA, a 'silver' penny.
Mercury works well with silver, but I'm not sure about copper. I would think that the mercury coating on a silver coin would only add milligrams to its weight. The other thing about covering a silver coin with mercury is that, while VERY shiny when done, it will dull within a couple of weeks. Electroplating works well on copper for both silver and gold. I have a gold plated penny, given to me by a company that does scientific gold plating. Still only worth 1¢. Bob
