Are metal detectors scams? Can you find copper coins?

Metal detectors are a lie. Even though they exist, you are wasting your life and money by using them to detect ancient coins.

Because it is so easy to make metal products now, there are discarded scrap metal yards everywhere, such as iron needles, broken iron and other metal objects. There will be a beep wherever you probe, so this method won't work.

Besides, only rare coins are valuable. Ancient coins that have been issued and circulated are basically worthless, and it is useless to find them. For example, copper coins with square holes are worthless in all dynasties. Therefore, making money by mining ancient coins is just a joke.
