Mis-sized (post decimalisation) 2 pence piece.

[impgreene]

I initially posted this under the “Free for all†section, but I suspect that was the wrong place, so apologies for the re-post.

All of my coins are pre-decimal, except one that is a 1986 2 pence piece that only has a side depth of approx. 1 millimetre (versus what my quick internet search seems to suggest is an ‘official’ depth of 1.85 millimetres).

The coin is pictured below.

It has all the definition of a normal width coin, so I was wondering if anyone knew if this is unusual and if the coin is ‘interesting’?

Thanks for any help you can give.
