Coins that are attracted to magnets and will stick to magnets are those coins that are made from either steel or pure nickel.
There's not any coins made today that are made of steel or pure nickel so you won't find any coins today that are made that will stick to a magnet or attract to a magnet.
But there were some coins made around 1943 that would stick to a magnet and one of those coins was a 1943 penny.
I forgot what the other coin was but I do remember the penny that my dad had that was made in 1943 and it was attracted to magnets.
I forgot what it was made of but it was one of the types of coins that would stick to a magnet but today's coins do not stick to magnets.
