Copper doesn't rust
it will probably take at least 5 minutes for a needle to rust unless it is copper.
NO!!! Because they are made of copper NOT iron.
In recent years pennies have been made of steel plated in copper, and steel is prone to rust. Older pennies were made of pure copper, or copper and zinc, which did not rust.
It's probably oxidation, not rust.
iron will rust faster because the hydrogen molecules combine with metalic molecules in the iron faster which causes the chemical reaction process to speed up sincerly, Jake from AZ 7th grade student

i dont know of an experiment to test this but copper will not rust, and bronze being comprised of tin and copper, the answer to which will rust fastest is steel. I hope this helps you.
a long time
