My understanding is that my Grandpa and Grandma bought a gold bar or a portion of a gold bar and were issued a receipt and the gold was either held by the bank that facilitated the deal or a third party. I am still getting details on which bank they went through and what bank acquired that bank etc... but my main question is:
What resources or options are available for tracking down this type of gold purchase? Are banks mandated to keep records on this type of thing and obligated reach out to the owner of the property?
