Gun store appraisals are different than gun store offers. Many appraisals are for insurance policies which will be high (similar to jewelry appraisals for insurance). Dealers have to buy low to make a profit, so their offers will be lower than appraisals.
I've sold quite a few guns for widows, never took a nickel, with only one question - do you want money fast or hold on for the highest price? Several had no idea what they had and the departed left no list/value. Bottom line is - they were worth what someone was willing to pay at the time.
It's been my experience that traditional M/L's are harder to move at gunshows and are not highly coveted items at auctions around here.
You are advised to see if any accessories, supplies are available as well.
