How to distinguish between copper buttons and iron buttons: Buttons for copper and iron materials, this is known with a magnet, and there is also a hard object to scrape off the surface plating layer and the brass color (gold) in the copper buckle surface. The iron buckle is black and this is the color of the raw material.
