Lol....I do not know. It was
good enough to have "copy" in small letters unlike so many
fake spanish coins (all very
poor copies). It was buried about 8 inches down-not necessarily originally-sands shift, people scuff up that same sand. It was alone. Most times at the beach, unless jewelery, one finds more than one thing buried i.e. several modern coins, not just one, that sort of thing. There was nothing around it.
You might be on to something. And actually on the coast of NC, real
spanish coins have washed ashore.
I salute whoever planted it. It was fun getting a signal, digging and lo and behold! a "piece of eight"!
I
hope whoever finds my real
ancient coins has the same fun.
And by the way, if Corona beer caps ever become valuable, I'll be moving to Capri and retiring!
