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.

Hi all
Thankyou for all your comments
Asto magnetic - zero
Absolutely nothing
That rules out nickel

I have checked the edge and we still have a silver look
Absolutely no copper or bronze look
But it has an overall steel look rather than silver
As it has no magnetic attraction (and I used a huge magnet) the look
Has me still gobsmacked compared to the other pennies - same era
Someone's been clever

Hi all
Maybe stupid question!
Could it be lead?
That's a silver looking material that's non magnetic ?
There's something very diff with this coin - it looks steel

Copper nickel coins are non magnetic, even with 25% nickel in the alloy.

If it's the same diameter and thickness as other 1906 pennies, it would weigh a lot more if it were lead.
See that little ding on the edge above and to the left of Britannia's head? Take a q-tip with some soapy water on it and see if you can clean that area.
It may show what's underneath if it was plated before it was dinged.
