Ah ok, well I guess one never knows when that pot of gold might turn up. I ran into a guy in the UK in 2018 when I was there who does what you do and turned up a Roman coin...Seems like it was a pretty rare one as he told me its value was around $10,000 apparently. He showed it to me...Could have been any old Roman coin to me, but it sounded impressive. Keep going mate, that nugget is out there!
