US coins have never been made of iron.
No US dollars contain iron.
The US has never made any lead coins, so no.
A magnet only attracts certain metals- primarily iron. Those old coins were not made of iron, but silver, copper and nickel. No reason they SHOULD be attracted by a magnet. Except 1943 US pennies, which WERE made of steel.
The first US nickels were made in 1866. There were no official US coins of any denomination made until 1793.
The US NEVER made any gold 1 cent coins
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.
The first coins made by the US Mint was in 1793.
No U.S. coins were ever made from lead.
Unless they are uncirculated or proofs coins made in 1959 to date have no extra value.
