No

Wouldn't fit in the coining chamber - a cent is 0.750 in. /19.05 mm and a nickel is 0.835 in. / 21.21 mm

Looks like plating flaking off.

Worthless. Well, still face value.

Hello and welcome.

It seems improbable that this could be a nickel planchet, for several reasons.

1. Nickel planchets are bigger than pennies; this seems to be the same size.
2. A nickel weighs exactly 5 grams; the mint tolerance for a nickel blank is a minimum of 4.8 grams. 4.3 grams would be seriously underweight; an actual nickel weighing only 4.3 grams and not showing an otherwise obvious explanation (such as acid damage) would be considered a mint error.
3. The coin appears to have a copper plating, just like a normal penny. the Mint receives penny planks pre-plated by the zinc company they buy them from, so the probability of the Mint wrongly plating a nickel blank is essentially zero.

This being said, the overweight nature of your coin does need explaining. 4.3 grams is considerably overweight for a penny, and would be considerably overweight even for a bronze penny.

You don't show us the other side of the coin. What I suspect we're seeing here is a magician coin, where a nickel has been hollowed out on one side and a ground-down penny stuck inside the hole.

I'll pile on for better pictures, especially of the edge. I suspect it may be in a bezel.

I agree with lcutler.
Being in a bezel would account for the magnetic reading and the extra weight.
Better pictures would verify this.

I realize sometimes the Mints quality control is a bit weak but not that weak!
