I will agree with all the above that older 22s just aren't worth a lot of money.
If you have any interest in shooting I would keep them. I inherited a pistol from each of my grandfathers. Both pistols were in calibers I don't otherwise shoot and I sold them. No regrets there, but if they were in 22LR I never would have sold them. You can never have too many 22LRs IMO. In fact I am using the money to buy a 22LR version of one of them. Down the road I may buy the 380 ACP version of the other.
If you only want to keep one I recommend you go to walmart get a 550 round brick of 22lr and find a place to shoot them. See which one you shoot better and go from there.
$0 of an NRA membership goes to legislative action or court battles. Not a dime. Only money contributed to the NRA-ILA or NRA-PVF.
Of course, you could just donate to the Second Amendment Foundation
I was feeling pretty good, then I looked around and realized I am not swimming or on fire.
