These were made out of brass so this one has either been plated or coated with something. Some brass is visible below the 3 and between the T H on the rim.

They were made of nickel-brass which isn't magnetic.
I saw some years ago a hollowed out threepence in which a small magnet had been inserted, so perhaps yours is one of these.
What's the weight, please ?

The 3 pence in this era are suppose to be made of nickel-brass. I used a strong magnet and it was attracted to this coin, not strongly but still attracted and attached. The traditional type or 'brassy' are not magnetic, the same magnet remains separate and inert. If the item is plated the condition is very good, (shiny like chrome but magnetic) it may be recent however the coin does not appear scratched or worn. This coin puzzles me as the plating is so uniform and nickel has such high melting point, I wonder why someone would use this coin as sceince experiment. More Comments welcome :)

Hi there apologies I can see this was put up a few years ago now but it came up in my research, I too have a silver in colour 12 sided 3d coin from 1938. Same design as the one in your image.
I have been trying to find information to try and establish why a coin that should be brass looking in colour is indeed silver.
My coin is unfortunately in a more worn condition than the one you have and as such I can see there are areas of brass colour showing through particularly round the edges. SO I do believe that is had been coated. However like you I have not seen any other ones of these around and am trying to establish if this was done by the mint as some kind of special edition or if it was something that was done afterwards by a private owner.
If you have any more information on these coins I would be grateful if you could enlighten me further!

School Science project electro plated? . Was all the rage with old british coins. More accustom to seeing them done with half pennies of which I had a few over the years. That was the official statement by The Royal Mint when I sent mine off for inspection. |

A plating of a magnetic metal can cause this coin to be magnetic. The visible brass beneath the stems of the thistle suggest that this is almost for sure plated I am afraid.

I too have one of these, but mine is in almost perfect condition.

Very old thread.
I recently came across what looked like to be an uncirculated off metal threepence, in copper nickel.
Knowing that it may have been plated, I knew that an XRF test would be of little help, because it only tests the surface.
So I took it to a professional coin dealer.
He remarked that he had seen a handful of them, over a period of decades.
His opinion was that it was standard threepence, nickel plated.
That opinion was based on the knowledge that quite a few of them were commercially plated post Mint, to be sold as cheap mementos of the Coronation of George V1, in 1937.
Some were holed for suspension
