Mind you @LawrenceChard, for some members these boating accidents are very real, in contrast to the coin if you ask me. 🙄
What is think happend; Back in 1784 when the Agencia Tributaria were actively looking for unsolicited gold and silver. The owner of this coin got cold feet and was afraid they would find his coin. So what he did was he quickly wrote a certificate stating the coin was found at the bottom of the sea. Apparently lost in a boating accident, which he happen to have found. 🙃
Edit: He used your initials for credibility as everyone already knew in 1784 you were going to be the leading PM dealer in the market. Foresight is a bliss!
