Most coins nowadays are not made of iron. Most coins in the United States are made of Nickel and Copper (small amounts of Copper in pennies).
Coins are typically made from a combination of metals such as copper, nickel, and zinc, but not iron or steel. Iron and steel are not commonly used in coin production due to their susceptibility to corrosion and their weight compared to other metals.
Coins are typically made of non-ferrous metals like copper, nickel, and zinc, which are not magnetic. Even if coins contain iron, the amount is usually too small to make them magnetic. Additionally, the process of minting coins involves heating and shaping the metal, which can disrupt any magnetic properties.
Old coins may contain iron or steel components, which can make them slightly magnetic. Coins made of metals like nickel or steel can exhibit magnetic properties due to their composition. Magnetic attraction to old coins is a result of the metal content within the coins.
the ones that lift up when you put a magnet over them.
If they were, they would rust too easily from the water vapor in the atmosphere and the oils from our fingers and be useless as they would not last long. Copper, nickel, silver and gold have become the metals of choice for coins as they resist rust.
Only those coins made from iron or an iron alloy, and that are rusty.
No US dollars contain iron.
All coins, even gold and silver, will tarnish, but rust is iron oxide, so only coins with iron in them will rust. The only ones I can think of are the steel 1943 US cents and some European Coins from the WW2 era.
COINS DUMBAZZ
US coins have never been made of iron.

Some do. You can use a magnet to find out which ones (the ferrous ones will be magnetic).CorrectionIron is not used in modern coins because it's too brittle. Many countries however mint coins from steel, but it's almost always plated with another metal to prevent rust.
Iron was sometimes added to copper coins as a cost-saving measure during times of coin shortages or economic crises. This practice was especially common during the late Roman Empire and medieval periods.
It easily becomes rusty.
Modern coins cannot rust, as they are not made of iron.
Apparently coins are made out of Iron, Metal, Bronze and other of types of metals/brass.
The element used to make permanent magnets and United States coins is iron. Permanent magnets are typically made from alloys of iron, while United States coins are primarily made of copper with a small amount of nickel (nickel-copper alloy).
