Found this but can't seem to find much about it no mint mark , not sure if this was a proof coin , One was plated in a gold colour but has been rubbed off not by me ,and the other still has the gold colour on but patchy. First one weights 3.18grams The second is 3.11grams Only info I can find is the 1970s mint mark As for the silver colour the 1974 Aluminum only and 1943 a steel Could this be a proof cent Any ideas ?      *** Moved by Staff to a more appropriate forum. *** |

Proof cents have an "S" mint mark.
People mess around with coins and plate them with zinc. Copper plating can change color through a variety of methods.

if it were a proof coin it would have a mirriored like backround and frosted devices, and I'm not seeing that. Plus, proofs were only minted at San Fransisco (S) in 1974
Most likley plated

So does this change the colour all the way through or just the top coat ? If the top coat how deep would this penetrate the coin ,,

I can say with near certainty that those coins did not leave the Mint that way.
Either plated or the victim of a high school science experiment.

The first one I have taken a little of the gold colour off as it was mostly rubbed off anyway so I took a little off and silver colour stays,
The second I haven't touched but the gold colour has been rubbed before I got it ,, I posted as yes I looked it up and they are minted with an s ,
That's what's confusing , if people muck around with zinc does this penetrate all the way through ?

Nope. Electroplating just adds a thin layer of a different material. Your splotchy cent is a good example of the plating coming off in some areas.

So if the one cent coin weight is this
"Early year coins, for example, weigh 3.11 grams, cents from 1943 weigh 2.70 grams, and the ones now in circulation weigh 2.50 grams."
Big reduction of weight in the 1943 on words even lower for up to date coins
Why on earth does mine weigh 3.18 grams could they be fakes then
I know the second coin has this gold plated on so did the first one too ,, as the colour is silver under the gold does this mean that just so I'm clear sorry to be a pain,,
A school boy / someone messed about with zinc then plated them in a gold substance , somehow changing the wieght too ,
Or do the weights vary anyways ,,
Are they just reproduction coins
Sorry for being a pain but if I don't ask I don't learn anything ,

The coins are real, but plated. When they plate a coin they may use different layers of different metals to get the final desired color. Thus adding weight to the coin. http://www.bestcoin.com/Plated-Coins.htmEdited by coop
