Cade,
I would recommend that you learn a bit more about the gun before you post it for sale. Getting it thoroughly inspected by a gun double gunsmith is wise (especially the bores). Then give it a good cleaning. After this get a few appraisals before you sell - just my recommendation, but you'll get a better idea of its real value - and you may fall in love with the gun
It's a nice looking gun. I'd recommend listing on this site - of course everyone here will want to know that it's shootable and will follow your progress in learning about it and getting it checked out, but that can be fun as well.
