It's going to depend on the buyer in this case. I like ivory stocks, especially with patina as this one has, but I'm really turned off by the bear. The engraving, although it covers a lot of area isn't executed as well as it could be which will hurt the value some. Or in other words, the better the engraving, the higher the value.
All that being said if it's a family gun I wouldn't worry about the value except for insurance purposes as I'd be keeping it and passinging it down to the next generation.
That really didn't help much did it?
