old share certificatesReport
Please briefly explain why you feel this question should be reported .
I am looking for help please! I’ve just unearthed some old share certificates that I am unsure are still valid. The first is for Marconi plc ordinary shares dating back to 2001-2004. The last letter I have from them is 2005.
The second is for mmO2 plc, again dating back to 2004.
Can anyone tell me if these certificates are still valid??
