Technically, you could say that, but probably not what you're thinking. It was plated with another metal https://www.sciencecompany.com/Turn-Copper-Pennies-Into-Silver-and-Gold-Pennies.aspx
Someone took a liquid metal like nickel or Zinc and covered the coin in question. Otherwise known as plating. Spend it.
This is done all the time. Science class experiments. Jewelers plate them as an accent to a jewelry piece. Tons of curio collectibles have plated cents in them. Time comes that the item they were plated for outlives it’s usefulness and the cents find their way back into commerce. I have two myself.
This cent looks like it was tinned with lead solder. Just heat up the copper, dip it in soldering paste and touch the lead to it and the lead will flow over the coin. My first 1869 IHC had this done to it. I recently picked up an 1853 Lrg Cent that was "silvered" also I actually got the lead out of the 53 making it a nice coin.
I got this silver 1995 from my mentor who took 8 to 10 of these from a single unc. shotgun bank roll. There is a old thread on google about them. Weather it is real or not is moot . They will never be collectible because the opportunity for fraud is so high and it is all but impossible to prove if the coin is a genuine mistake.
And almost everyone that ever goes to work for a company that does metal plating does it to some coins as well. That seems to be an almost universal urge.
