Here is my estimation. You should do a little better then breaking even.
Looks like an AA barrel, stock body, classic valve and a benchmark or Dye double trigger frame. That micro line has to go though. On eBay, I'd say $100
Micromag: You did good here. Looks like a 3rd Gen. Has a Stiffi and the hard to find VA. If you really wanted to sell it, you could probably get $200 but not much more. Again, eBay
The worst of the bunch. Bare bones basic Mini. Can't tell the barrel, but that microline has to go. I'd say $80-$90 on this one.
You're in the black on price though
