i found this penny yesterday. It’s a 2012 (D) Lincoln shield penny but it’s silver. Is it possibly a penny stamped with a dime planchet? I have no way of measuring how much it weighs.
No, it's a plated cent, done as a novelty item. If it were struck on a dime planchet, it would be about dime size, and you would have outer clad layers and a copper core showing, just like a clad dime. Your cent is full diameter, and it will weigh just a tad more than a normal copper-coated zinc cent, due to the plating.
