How did you determine that the coin you have is a bronze nickel steel planchet? XRF analysis? How much does it weigh? Do you have pictures?
Jennifer, I have a 1964D silver penny. Seems odd that all the talk on here is saying no they are nickels or 1973 pennies but the real buzz is many people have put their hands or eyes on a 1964 silver penny. Mine is non- magnetic and I have no scale that will weigh that small of an amount. Obviously it's a real thing but no one has the answer to what they are.
Obviously not.. Obviously Plated By the way.. The person you quoted was last seen here in cointalk on September 11th 2014. Look at the dates of the thread before quoting a long gone poster.
Mine is a 1964D. I saw the mercury plating video, that probably wouldn't add enough weight to tell if it's heavier than a copper penny but don't know for sure. Strange problem and if mine is a "D" I would think if minted that way it would be exclusive to Denver Mint. No one else has claimed their's is a "D". They must be plated or something but not enough of them to find out any good info.
I read one post about 16 steel pennies were made and given to Senators. When asked to return them only 8 came back and 1 is in the Smithsonian while 8 are MIA. If you have one that came from under an escalator at Congress that could be the real deal if this is true. My 1964D is not magnetic. I wonder if the blue tint non magnetic's are mercury plated ones that someone made to pass off as the real deals? People do dumb stuff like that. I will check back occasionally to see if any more info comes in. Hold on to your steelie, could be a retirement fund.
Many, many cents were plated AFTER they left the mint. It was great HS science chemistry that allowed the student to take the science home with them. Since they were not minted like this, collectors consider them to damaged coins and are only worth face value. You advised people to hold onto them because they might be a retirement fund. That is very poor advise, but if you believe it, then here are some links that show you how to make more. You only need to make about 100 million to have that $1,000,000 fund https://www.sciencecompany.com/Turn-Copper-Pennies-Into-Silver-and-Gold-Pennies.aspx https://www.msn.com/en-us/tv/news/science-sunday-an-experiment-in-electroplating-pennies/vi-BB1aLLha https://www.finishing.com/plating.shtml
Or struck on a dime planchet. He hasn't shown pictures or given a weight so that can't be ruled out. Those were aluminum cents not steel and that happened in 1973. (the aluminum cents were dated 1974) There were experimental 1974 steel cents as well but they were copper clad steel so they weren't silver in color.
