I have found some shares in Rayrock Resources Limited and wonder if they have any value
Jill, from the information I have available:
Rayrock became Rayrock Yellowknife which went through several mergers and became Goldcorp. Therefore, if the certificate is valid and you can prove legal ownership of the underlying shares and not just the certificate, it might have significant value. You will need to contact the current transfer agent for Goldcorp, which I believe is Canadian Stock Transfer (www.canstockta.com) to determine what value, if any, you can obtain from the certificate.
