An old monkey in need of a little help - I've been living overseas and come back to find my share certificate from Igas energy saying, Ordinary share price of 10p each - My question is; the current SP is about 25p - so is it the current shares priced multiplied by the number of shares or 10p.

I've only got about 4000 share that where worth something years ago, I stupidly held on believing in Scotland CBM and that it would turn around - stupid, stupid monkey.

No doubt an easy answer that I've missed - Kind regards for any help offered - Sean.

PS - Next I have to work out what to do with them.
