The type is Capped Bust, Lettered Edge. The Overton variety is a matter for specialists to tell you. Low grade, but I like it. It's a CircCam.
As said above, the type is Lettered Edge Capped Bust. The variety (which you were actually asking about, I believe) is 1824 over a recut 4. The Overton die marriage is O-110. Nice pick-up.
