[ashleighess]

Hi,

i have this 10p which is unusual and has smooth sides. Not seen another dated 2015 and just wanted to know if it was worth anything?

thanks

Looks like it could be struck out of collar? Not sure how popular error coins are in the UK but here in Australia you could sell it for tens of dollars at least.

Nice find anyway - normally the mint should pick this up, or at worst a security company's rolling machine should reject it - they don't often get to circulation.
