1970 waterpump worth anything?

this would be for the number matching small block people. (probably few and far between). Anyway my new to me motor had a waterpump attached to it but after filling it with water I got a small leak out of the weep hole. So out it went and bought a new checkers waterpump, and since its new they dont need a core.
I got to looking at it and its dated A 28 70, so I was curious if its worth anything before it goes into the scrap pile.
Hey Justin (chef) are you looking for a correct wp for your 70? jim
