Black maples, now considered a type of Sugar Maple, are not common.
Here is a page from the Maryland Biodiversity website that lists a small number found in Harford County: https://www.marylandbiodiversity.com/viewSpecies.php?species=1480&showHidden=1
We can't really tell from your photo if you have a black maple there.
They tend to have less lobes (points) on the leaves, which are often droopy, with hair on the undersides.

It would not be unusual to have a Norway Maple, as they were once widely planted and often self-seed. If the leaves are still fresh enough, an indicator that it's a Norway is if the leaf stem bleeds a white, milky sap when separated from the twig.
They also tend to have flatter seeds on the samaras (the helicopter-like seeds that drop), than black maple, which are kind of bulbous.
