About 20 years ago I had a short period where I made some small investments in shares. I have a dozen or so certificates from that time but I don't really know which are still of value.
Some of the companies probably don't exist anymore, having been taken over, but that could mean I have shares in the new company, or (more likely?) I received a cheque at the time of the takeover.
For those that do exist, there are multiple certificates, does that mean additional shares have been issued to me or that the new certificates are replacements?
How can I find out what I actually own?
