Are the ancient coins bought at the stall genuine?

It's simple. Everything in the stall is not necessarily fake. As long as you have an eye for pearls, you will also find them. Fake ancient coins are generally made by copper plating on iron tires and then moderately etching. If you put them next to the magnet, they will be attracted by the magnet. Of course, some of them will be made of other metals, but you will find it true and false when you weigh it.
