The three main alloys used in the manufacture of coins are nickel-brass (mainly copper, with zinc and nickel), cupronickel (mainly copper, with nickel), and bronze (mainly copper, with zinc and tin). Copper and its alloys can be easily made into coins, and also show good resistance to corrosion.

How can you tell if a coin is brass?
Determining if a product is made of brass is pretty straightforward. Brass items usually are yellow, so if the metal doesn’t contain a tint of white-yellow or dull-yellow, you can generally rule them out. You can also look for signs of wear and tear. Real brass will stain, and fake brass will rust.
What is the difference between a copper penny and a bronze penny?
A penny is not what you think. Indeed, from 1793 to 1837, a cent was pure copper. But newer pennies are made mostly of zinc. The cent was again bronze (95 percent copper, and five percent tin and zinc) from 1864 to 1962, except: In 1943, the coin’s composition was changed to zinc-coated steel.

If clean and not oxidized, the brass is a golden yellow color and the copper is reddish brown color we call copper color. If it is old, circulated coin and has been handled by many hands or left out in the weather, then it will have a patina from oxidation.
Is the Lincoln Penny made of brass or copper?
I just found a modern (1994 D) Lincoln penny that is a different color than all other pennies I have ever seen. It is more yellowish / brass color as opposed to the usual copper / reddish. It seems to be made of different alloy. It is not surface-polished. The coin is the same color below the surface. Is this unusual?
Why are there brass pennies in the 90’s?
The “Brass Cent” of the 90’s are an error caused by the coins sitting in a chemical bath. The zinc and the copper collect in the tank and coat the coin with the “Brass”. You wouldn’t see this error on the pre-zinc pennies. — Brian –.
What kind of metal is used in penny coins?
As the price of copper has risen, so bronze is often being replaced by a copper clad metal of lower value. Examples are the copper-clad steel of UK one and two penny coins, and copper-clad zinc used for US one cent coins. Bell Metal and Bath Metal are other types of bronze.
