This is almost certainly a partial collar error, notice the "railroad rim" like edge of the coin, that is the hallmark of a partial collar error. This is a rather large one, most of the ones that escape the mint these days are relatively minor. For common Lincoln cent dates, these have been going for $5 to $10 on ebay over the past few months. As I see no 2020 examples sold or listed for sale, this one would likely go for more than that if you were to put up for auction now. If more examples hit the market, expect the price to fall back down to the $5 to $10 range eventually.
Good find! Definitely worth keeping!
