First, welcome to the forum. Unfortunately there is no real value in those coins, they are just damaged. I would hang on to them though.
Welcome to CoinTalk! I don't think that it is worth getting those coins graded. The environmental damage retracts any true value like l.cutler said. I would still keep both. After all, $0.02 is not worth anything.
Here are a couple of sites with good info. https://www.pcgs.com/Photograde/#/Lincoln/Grades. https://www.usacoinbook.com/coins/small-cents/lincoln-wheat-cent/
