Counterfeit or Error coin? Answered

Hello,

I have a 50 pence coin that I noticed because it was not accepted in a vending machine.
On comparison with another coin of the same year it became obvious that something was awry.
I don't mind because I like fake coins, they are interesting.

It is noticeably thinner and at least a gram lighter; it just feels less substantial.
The rim on the upper half of the coin on both sides has either worn away or was never there.

I looked on the Googles but can only find information on counterfeit pound coins, of which there are millions ( between 1:50 and 1:200).
It seems that a 50 pence may be too low in value to fake.

Are there any coin collectors out there who know whether this is likely to be a fake coin or an error coin.

If it is an error coin does it have a value.

Thank you.

PS
Through reading around, I discovered that the 50 pence is a special shape; despite its  odd shape it has a constant diameter.

If it is significantly light or heavy it's a fake.

The 50p shape is very cool. One of the consequences of having a constant diameter is that it will roll smoothly, without bouncing or skipping.

You can't use the shape for a wheel, though, because even though it rolls smoothly, there is no single center of rotation -- put onto an axle, it (or the axle) will bounce up and down seven times each revolution.

Errors are not thinner and wouldn't be that warn looking. If it is a real coin that has been overly abused then take it to a bank and have them check it out. They can tell you if its overly warn or a fake.

A coin collector's shop is also a good bet.
