We are not actually shown the process of anyone there detecting then digging it out. Could simply have been planted there. The coin, if real, looks like in mint strike condition....could be worth lots of money. .
Not all finds are "live" digs, for the simple fact that a lot of garbage is found, including false readings. I'm not familiar with this guy's channel, but it does seem a bit suspect. Eh, who knows..
Clearly the insinuation of the person in the video is that he and some others were actively detecting and as a result found that coin. It would take no more effort to crop the video prior to the first detection of the coin under undisturbed sand as opposed to cropping the video where it was unless the video wasn't started until after the coin was dug up. But that is what is suspect to me since gold has a different reading (on every metal detector that I'm aware of) than other common metals found at the beach. .
Begs the question, though.. Is the year 1541 really considered "medieval"? I've got one dated 1538, and I don't consider it as such. "The most commonly given starting point for the Middle Ages is 476, first used by Bruni. For Europe as a whole, 1500 is often considered to be the end of the Middle Ages, but there is no universally agreed upon end date. Depending on the context, events such as Christopher Columbus's first voyage to the Americas in 1492, the conquest of Constantinople by the Turks in 1453, or the Protestant Reformation in 1517 are sometimes used. English historians often use the Battle of Bosworth Field in 1485 to mark the end of the period. For Spain, dates commonly used are the death of King Ferdinand II in 1516, the death of Queen Isabella I of Castile in 1504, or the conquest of Granada in 1492." https://en.wikipedia.org/wiki/Middle_Ages
Your comment made me laugh. I noticed it too, especially when he laughed exposing his nostrils. Honestly the coin looks dodgy in my opinion. But on second thought, he wouldn't post it on YouTube if the coin is not real. I am not certain if he already have it checked from an appraiser.
