I just watched an episode of the show. The lady went to sell a ancient coin. He immediately recognized the coin as a denarius Ancient Roman coin. You could see the Greek letters on the coin and he was 100% sure that that coin was a denarius. He said “I don’t know how much it cost so I have to call an “expert”. (I don’t know how much expert he was) He check the coin and he said “Yes it is an ancient Roman coin I just check online, and I m not an expert and I found that the coin is Ancient Greek from Mithradates VI Eupator king of Pontus. I thing the people who visiting the place they don’t know what they hold on their hands and the “experts” either they are not experts or .... the comments are yours.
