I just obtained a mint, in box, NEVER FIRED (except for the intial test at the factory) Crosman Peacemaker 44. It uses .177 pellets and 12g C02 cartridges. My father gave it to me. I believe it's from 1975. Any idea of the value of this? I don't want to shoot the thing if it's worth a decent amount.

I also obtained a Slavia 618 and a Daisy Powerline 1200, but I have been shooting targets with them .

Any info on the peacemaker would be appreciated. Thanks.

I think you'll find that a really nice one in box fetches $75-100 on auction websites. But you might want to enjoy it instead of just packing it away in the closet (of course, by now the seals are likely dried up)
