Welcome to the forum.

The 1943 cent was the only one minted in zinc coated steel. The three '43 cents - one with no mint mark, one with a "D," and one with an "S," should all be strongly attracted by a magnet. The 1944 was minted in bronze, which should not be attracted by a magnet. None are especially valuable, unless in almost perfect condition. And, by "almost perfect," I mean absolutely no wear, and only one or two tiny tics under 5X magnification. Additionally, replated steel cents are worth very little. If the edges are smooth and shiny, they have probably been replated

Difficult to say without some photos and an accurate weight of the coins in question.   For the one that is not attracted it could be one of the many high school science experiment coins that have been coated with something.   Not uncommon, also there are numerous fakes that can be purchased from unscrupulous seller abroad and it could be one of those.

Sounds like you have three 1943 steel cents and possibly a 1944 that someone has plated.  There are a FEW 194 cents known struck on steel cent planchets and those are very valuable.  Which is why someone plated the 1944 cent.
