double barrel 12 gauge

Hey everyone.i am looking to sell this double barrel shotgun. It was my grandfathers and I have had it for 25 plus years. I don’t remember him using it much and neither does my dad. My dad said grandpa owned it for years. It has the names C Moody and Ramsey on it. Matching serial numbers and some marks etc on it as well. There is a little bit of information on line but not a lot. Lots of pattern work on it and I am guessing all Damascus barrel. Seems to be very well done.  I would like to sell it but not sure the value.  my grandfather did say he was offered $5000 years ago. But not sure the whole story. You can text me at +17805145829 or use the message system on gunpost. Thanks.
