I don't imagine they're worth more than you paid for them. These are Italian machine engraved replicas with plastic stocks.
I used to run into this all the time when I ran a gun store. Somebody would bring in their limited edition Winchester John Wayne commemorative model 94 (or whatever) thinking that twenty years had added a lot of value and hoping to trade for something or sell. A quick check of the Blue Book would show these had little to no value over working guns in the same condition. And that was with Winchesters, Colts, etc, made by Winchester or Colt. Italian replicas are liable to be worth even less than you paid for them.
These kind of guns look nice on the wall, but as an investment they're a bust. So, build or buy that nice case and enjoy them.
