£25 Mule Coin Trying To Find Any Information

Hi paddy
Its composition is copper I just assumed a mule was some type of dye test coin. the link you provided is definitely this coin, however the coin in the link is solid silver I can recall seeing a gold one also.
I can't find any way to value it most of the free online coin valuation service either don't reply or tell me they are unsure of value
Thanks for taking the time to respond.

And just to clarify: a "mule" is a specific kind of mint error, where two dies from two different coins are accidentally used together to make a coin. Like using the "heads" side from a 2p coin and the "tails" side from a 10p. Or a New Zealand 2 cent "tails" with a Bahama Islands 5 cents "heads".

What you allegedly have would be a "wrong planchet", where a blank metal disk that was the correct size, but made of the wrong metal, was fed into the dies. But I would not be entirely certain of this - I suspect it might simply be a normal silver coin that has been plated, either by the mint that made it or by someone else. Don't know why anybody would take a silver coin and copper-plate it, but people do odd things sometimes. I am inclined to think this, because looking at the rim, down below the words "Victoria" and "Pounds", the copper colour seems to be wearing off, showing a more silvery colour underneath.

What you'd need to do is to weigh it. Getting a specific gravity (density) test on it would also help, to determine what it's made of, whether it's solid copper or just copper-plated.

Honestly gentleman I can't thank you enough for the information you have provided its much appreciated
