2006 Brunel £2 Coin With Error

Unfortunately it's another case of "don't believe what you see on ebay" or other unpoliced selling platforms.

Firstly, there is no such thing as "upside down edges" in modern coinage. The manufacturing process means that roughly 50% will be one way up, and the rest the other.
As to the uneven dots - The Royal Mint's quality control has declined enormously. Almost any of the two tone coins (£2 and £1) will have variations in the size of the dots. That doesn't stop online sellers from trying to make a quick buck by selling them as "error" coins.
The other common scam is to claim that the insert is upside down, twisted, or the wrong one for the date. All these are impossible in the manufacturing process and have been achieved by unscrupulous sellers punching the centre disc out and replacing it incorrectly.

There are rarer variations around - having the wrong edge lettering for the coin design occurs occasionally, but again be aware of fakes.

Thank you for the reply Paddy, I found this coin in some change I received so doesn't matter to me if it's worth anything to be honest it's just something I hadn't noticed before! Do you think it would be worth anything to any collectors or am I just better off spending it? I'm not looking to make easy money just wondering if it is of interest to any collectors to be honest.

Thanks again.

Ok fair enough,

Thank you again for the help.
