9 inch artillery shell completely empty

Open the  as I need to Downsize stuff Not really sure on price, but probably 50 bucks in brass alone don’t know anything about it other than it was manufactured in 1977 it is fired off. It is just an empty shell casing. Cool display piece. Might be interested in trade for a live ammo in 22lr or mag or17hmr or 30-06 or 303 Brit or 12 gauge or 20 gauge  maybe a optics or single shot  firearms  no pal required
