The weight is normal for a circulated example. Beyond that, I don't know.

Old pennies got treated pretty harshly by some people - the combination of a large size and low face value made them ideal for 'experiments' by schoolkids. Maybe it's been plated with mercury - a thin coating probably wouldn't have a noticeable effect on the weight.

@pshann, I agree with @nr about a coating such as mercury have been applied to this in the past.

You could bring it to a local university and have an engineering prof run one of a variety of non-destructive tests to look for evidence of nickel or chromium (if it was plated at one point) or mercury. For example, most scanning electron microscopes have an Energy-dispersive X-ray spectroscopy attachment. X-ray fluorescence might also give you the answer.

Billions of coins circulated for 100 years among millions of people. If it is conceivable and physically possible, it has happened.

I would assume that it had been plated. A penny is about the same size as a florin, or maybe a halfcrown (it's actually between the two). The two coins have the same obverse. So, silver-plate a coin, pass it over heads-up, and hope the merchant takes it for a florin. It's illegal to do this, of course - plating a coin to make it resemble a higher denomination is specifically prohibited by the Coinage Acts (or equivalent legislation) of most countries, including Britain. Depending on the laws where you are, it might even be technically illegal to own such a coin.

If it is nickel-plated, it may be attracted to a strong magnet. You might as well try that test.

If a copper alloy coin has the misfortune to be nickel plated,
it nevertheless will not be attracted to a magnet,
simply because there is not enough nickel in the plating to have sufficient magnetic influence.
The weight of the copper core is enough to overcome the magnetic attraction.

Pure nickel coins are very obviously magnetic.
