About G-6, I'd say. Rim wear. And probably cleaned. I'm thinking 15-20 $. But maybe I'm being hard on it.
As a collector of both cap bust half dimes, as well seated half dimes .....the op's coin is a detailed dug coin, in G 4/6 condition at best, the die marriage is a very common one, this specimen isn't worth $60/$70. G04 G06
