Good Day All I am a newbie... I spend more time browsing than posting, as I enter thhe exciting world of coins I depend alotr on the information that I find on this forum, the feed back one receives here is authentic and backed up with knowledge. One thing you can count you will receive the information that you need to hear and not what you want to hear. I came across a 2000d penny that was silver I thrill to find it, I assumed that this was going to be a winner. I did my research aswell as scratching my own head as to how and why this coin was like this. Seeking for imformation I could see that there was still nothing conclusive on how these coins are in existance. Mine has a normal weight and is not magnectic its only problem was that the copper was completeley off. This is one heck of an error and I just could not see how this was possible. I went to a friend of mine who does trophys and medals and does his own electroplating I was hoping he could confirm it to be electroplated. I left the coin with him and he phoned me few days later to come and collect my coin.He gave me 2 silver coins back and said that its not electroplated and it was the nickel composition that I was seeing. Basically this coin can be brought to this beautiful shiny silver in your kitchen with no chemicals at all.He used a polish that he uses to polish perspex sheeting to bring it to a nice shine as it is non abrasive. I am not by any means saying that all of them are made this way, I have done the research and would like to share it with the forum and hopefully avoid somebody paying for something that is not what they believe and it could be consideration next time one pops up. The 2000 d is the one I found The 1996 d was my sample copper coin that I took with and was returned to me silver. The 1996 p was my shot at doing it, it jusst needs to be rubbed wwith some perspex polish and I will have a shiny silver coin. I will post the result tomorrow nad let you know how I achieved it.    |

@wulff, can you please post the weights of these coins? I'm wondering if these are silver or merely silver-colored. I suspect that you may have stripped the copper plating off leaving behind the zinc core.

The same effect can be done by rubbing them with mercury. Use to do it all the time back in the 60s. It's frowned upon now, something about being dangerous to your health. I haven't seen any sign of it yet. I haven't seen any sign of it yet.  Oh and  |

Actually it is plated over the copper layer. Note the split plating plated over again on the 'N' on cent. Just altered surface coins making them just face value coins.

perspex polish is for plexiglass and acrylic, it is an abrasive, it's a very fine abrasive though use to polish clear plastic. probably polishing off the thin copper plating and exposing the pure zinc underneath. you can also see the fine scratches in these pictures if you are looking for it. none of them have the strike flow lines you'd see on a struck unplated planchet.

Since mid-year 1982, Lincoln cents are no longer copper. They are zinc plated with a fairly thin (8 microns) layer of copper.
A few unplated planchets have been struck. They are well-struck, with no copper residue in the corners. These are genuine errors.
The are fakes:
People also remove the copper plating with acid. Getting all the copper off without removing some of the zinc is nearly impossible, so they either show copper residue in the corners of letters and/or the details are mushy.
Lastly, people plate the coins with nickel or chrome. You may see the shadow of the copper if the added plating is too thin, or the details get mushy if it's thick.

just a penny that the copper coating has been stripped leaving a zinc finish which looks silver but its not, its also not a steel penny cause doesn't stick to a magnet, we see lots of these everyday, all it is is a bunch of ruined pennies worth one cent and nobody wants them
