I think the Ruger OM 357 is worth around $450-$500. They used to bring more but the market is a little soft on them right now. Yours is in good shape, unconverted, with original grips, and is a non-prefix s/n, so all of those things help. Might be able to squeeze a little more out of it, if the stars align. I have a nice shooter grade gun listed for sale on Gunbroker now at $475 and not getting any action.

The Colt is probably worth in the $1500 range. It's a nice gun, good condition, a series 70, and in 9mm, so those are all good things going for it.

If you decide you want to sell them here, drop me an email and we can discuss off-line. If not, no problem and good luck with them, they are both good guns.

Just my $0.02

In full disclosure, I would have no problem selling to someone helping give a current market value, I've done it before, and will again. I trust this group to give honest opinions.
I haven't kept up on current prices on this stuff since I'm not in a buying mode, and real world post election pricing might be way off from what I would SWAG.

First;
Ruger Old Model BlackHawk 357 in original configuration (ie. not converted)
4 5/8"
It's ridden in a holster in the safe except for the 2-3 times the original owner (my buddy's father in law) took it to the range after he bought it in early 70's?
Slight thinning on muzzle edges and ER housing from holster wear.
Almost no turn line.

Second;
Colt's MkIV/Series 70 Government 9mm Luger
Original configuration
Hard to find any bluing wear, it's just started on the flared muzzle on the barrel.
100-200 rounds through it all at the range.

Picture hosting is an issue lately, but I will try to get pics up shortly.
