About 20 years ago I was given some shares by my employer, the dividends from which arrive in the form of more shares. I now have a large pile of share certificates and I want to sell the lot.
I've never sold or bought shares before and I have no long-term interest in share dealing. I presume I need to take the certificates somewhere... but where? Is it safe to send the certificates by post? What is the best way to sell these?
