Old Bank Safe - How To Proceed?

I would have a key made for it, and if it didn't sell I would keep it for myself. I sold my safe when I moved and don't have one now.

Absolutly sell outright, list it on craigslist Looking at the welds and size you have no problem getting 300. for it as is. I sold a smaller one that was drilled out fo 450. Good Luck

My yard won't take any safe, they right away assumes they have cement. So yes try to sell it..
