Two coins from two famous shipwrecks: Hollandia (1743), and El Cazador (1784). Both were made in Mexico City and forned part of the massive dependence of the 18th century world on Spanish silver. Close-ups of the coins and their return to Mexico City in July 2021.
Regrettably, I have had to turn off the Comments facility. YouTube now requires 2-step verification for YouTube channel users like myself. This is incredibly tedious, largely because I have constantly to monitor the comments for the small number of viewers who abuse/misuse the facility by making inappropriate or personal comments, try to contact me about issues unrelated to the video in question sometimes in a completely unacceptable way, and there are also the robots that inject obscene or other unsuitable content. Each of these has laboriously to be deleted which means constant 2-step verification every time. So, Comments on my videos will now be permanently disabled. Sorry.
