The rare British coin that's worth £200,000 - here's what to look for
An expert reckons it's worth "looking out for" a unique British coin that's worth a small fortune. If you find a proof penny from 1952 it could be worth a whopping £200,000. As they are special early samples of a coin issue, proof coins differ from those you would find in circulation. They are also the highest quality of coin a mint produces.
