The upper Smith would appear to be a pre-WWII .38 Hand Ejector, essentially an earlier version of the Model 10. Model numbers didn't get assigned until roughly 1960. The serial number should be on the button of the butt, which would help to narrow exact engineering change and rough year of production. In that condition, assuming fully functional with good bore, it's probably $300-400 in the current market.
The lower one is probably a Spanish or Belgian knock-off and has real value only as a wall hanger, maybe $100-200 for somebody who thinks it's cool.
