ACw was used 50-51. Yours is a 1951.
Girls bikes aren't worth much, and yours is a low end model. Looks like you are missing quite a few original parts. Fenders, bars, crank/sprocket/pedals, rims, tires. Not sure about the seat.
I have a thread in the Gallery section for Cleveland Welding bikes, you can look there for paint schemes
There should be a series of numbers on the headbadge, can you post those?
