This coin is in such poor condition but the not knowing is killing me. It is very heavy for its size but to the best of my knowledge gold wouldnt look like this so it has me thinking of bronze. The shape on the coin looks almost like a Spanish coin- maybe Carolus III but he is facing left. The back looks somewhat like a Mercury dime. With it's condition it has lost numistic value, so I lightly filed the edge and it has a gold color(so would bronze though) As you can see by the scale its heavy. ANY IDEAS?
Would shipwreck gold corrode this badly, it also looks like someone tried badly to scrape it clean. At this point it just about knowing what it is and maybe there is metal value to it anyway.
It is some sort of Louis XVI I am guessing. Looks like this 1792 2 Sol. You can start your research there.
Because it contains nearly an oz of copper. This was back when a coin was expected to have close to its face value in metal content. At that time 2 sols in silver would have been less than half a gram in weight (about half the size of a three cent silver). this would be too small to handle so they used copper. But that made the coin weigh close to an oz (There was also a copper 5 sols token privately issued that weighed nearly two oz)
