Unless that's a Tula 91/59, not rare at all, round receiver, not hex- and not worth two bills even as a collectible.
The Mauser otoh, looks like a beauty. I'd take it for two bills in a heartbeat if it has a good bore and crown.
FWIW, I'm a big fan of the MN, I have two, one highly "sporterized" that I use for long-range- they can shoot if you have one with a good bore.
Buy a 91/30 for $90 online if you want one to shoot...
There's a lot of "inflation" going on with Mosins these days at retailers and some online vendors. Shop around, they're still available at sub-$100 prices easily.
