I have a paper share certificate for 6667 ordinary shares with Milwall Holdings PLC. these were purchased about 25 years ago I don't think they are worth much but want to sell them anyway. Any idea how I can get their value and which company to use to sell them (pref by phone). Thanks
//Firstly email them and ask if your shares are still valid.//
That's a very good idea. That company currently has 8,386 Ordinary Shares of £10,000 each. More than 90% of those shares (7,813) are owned by Chestnut Hill Ventures, which in turn is controlled by James T. Berylson, a non-Executive Director of Millwall Holdings.
Something may have happened to your shares in the last 25 years.
