Can anyone give me some info on these 2 guns and what they are worth?

nothing on the SKS but the little single shot is very interesting looking. following to see exactly what you got.

I believe the second rifle is a Stevens Crack Shot. I have no idea what it would be worth.

The first is a SKS and looks China made. Sell from $400 to $500 depending on condition and manufacture. The second looks like a Stevens and it depends on chambering. If it's a 22 , they bring good money. If it's a 25 or 32 rimfire, not so much. If it's one of the few chambered for a 32 S&W it has good value. Depending on condition.

The SKS could be anywhere from $300-600. All depends on numbers and pedigree.
