Antique golf irons w/ hickory shafts and leather grips

Help! I have some golf clubs that my father left me and I'm trying to figure out what to do with them, or if they are valuable. I have a Hillerich&Bradsby Louisville KY, Bonnie B Mashie and perhaps what I think the oldest is S.D.&G iron which does not pop up anywhere when I Google it. My father and mother were antique dealers and collected things like this so there is no telling how old they Canby. They are Hickory shafts and the grips are still very much in tact. I'd Love to hear from you to see if you could give me some guidance on these. I live in Atlanta Georgia. Thanks much!
