Any ballpark guess on value?
A quick look see on GunBroker shows asking prices ranging from $125-$250 for well used (rusty blue to aging nickel) with clean models going from the 4's to 5 range, so if it's a good friend, I'd feel good about $350 each and could sleep well at night.
But again, your location might have certain variables that alter real life prices somewhat (CA and MA come to mind).
A free people ought not only to be armed and disciplined, but they should have sufficient arms and ammunition to maintain a status of independence from any who might attempt to abuse them, which would include their own government." - George Washington, January 8, 1790, First State of the Union Address
