l find 5 medieval gold ducats in 1o meters in diameter..all of them are as new..a little dust and thats it!!!
Wow, that looks like fun! I'd give anything to be there with you! Does gold stay together better in the ground? That thing hardly decomposed at all, I'd imagine it does.
Gold is an element (a metal) and in its purest form is almost completely chemically inert. This means it won't react with anything found in the ground and atmosphere, and will only ionize under fairly extreme conditions such as high heat or very toxic chemical solutions (nitric + hyrochloric acids combined). Roman aurei were as close to 100% pure gold as the Romans could create, at least through the reign of Claudius. So aurei found in the ground anywhere are very likely to be in the condition that they were when buried. The Claudius aureus found in this video has a portrait that many (not all!) consider the most artistic of all Claudius aurei. A recent example sold for around $36,000 (not including buyer's premium) at May's NAC auction in Switzerland:
That's the club I went detecting with in England. I did not meet ChicagoRon - I was in a different group with LouisianaSal. They called me "GARobertson". I remember that aureus video. I watched it a few days before I went on my trip and it had me practically hyperventilating.
