I'll safely assume that's a "Marlin" bolt action SG.
Of the two, the .22 is actually more valuable. Prices ranging from $350-650 on Gunbroker and Armslist. A couple of folks are asking more, but likely nobody's taking it. I'd say asking $500-600 depending on surface finish and bore/parts wear isn't unreasonable.
The shotgun...isn't necessarily that valuable. Is it a Glenfield model? Should be on the receiver stamp somewhere. But I'd say between $150-250 will be about what you're going to get. They just aren't that popular.
These prices are through private sales only. The 39a has an almost cult like following when it comes to .22 repeaters and you'll get a far better price from someone either looking for a nostalgia shooter or to replace one they might have sold years ago. The date is what can help sell it since the guns built in that time frame are considered "better" quality than the assembly line production pieces today.
Fun fact, the Model 39a descends from the Model 39 which in turn descends from the Model 1891, the same rifle Annie Oakley used in her exhibition shooting.
