In case you’re curious, Wikipedia explains about the steel 1943 US penny (“the only regular-issue United States coin that can be picked up with a magnet”) and the large Eisenhower dollar (“the new dollars failed to circulate to any degree, except in and around Nevada casinos, where they took the place of privately issued tokens”).
