thank you
 

This has certainly been interesting. Thank you to everyone who has shared insight. I am trying to wade through the politics of the situation. At this time, let's just say all family want to be fair. "Uncle Frank" understands would like to pay a fair price-- similar to what it could go for in auction; not a discount. At this time, I am trying to avoid contacting Julia's for their "free estimate." Again, thank you for your valuable insight.

You can look on Gun Broker, Guns international and see what similar guns to yours have sold for not the asking price. More detailed pictures of the gun would be helpful.

I don't know where you live but you could take it to a dealer with a good reputation for an estimate in writing of it's value.

I have several DHE 20's of varying barrel lengths and the most I paid for one was $13K in excellent condition with a good amount of case color remaining. If I was looking for a straight grip 20 (and I love a straight grip small bore) I think your gun would be valued at between $8K-9500.

It's a nice gun with several very redeeming factors such as ejectors, unmolested original condition, straight grip and I'm assuming the skeleton but.
The most important thing is it will stay in the family for future generations and your family member is willing to pay a fair price to keep it in the family.

A little late to the party, but considering it is a family gun I would operate from around the $6000 range. Sure you are probably leaving a little money on the table, but unless Uncle Frank has an unlimited bank account there is no real reason to bend him over the table on price. Unless there is a drastic need for the funds that is. When it comes to family it isn't worth hard feelings over a small difference in price. Giving him a bit of a family discount. Also, is he buying the gun entirely or just buying out the rest of the family's interest in it. Because if it part of the estate, he could technically have a claim to part of the value of the gun.

We still have not been told the length of pull or butt treatment. In case that doesn't mean anything to the price, I have a pair of nice original DHE 20s with 13 inch stocks, recoil pads, that I would be happy to sell for about half of what some here are mentioning as the right price. Skeleton butt, 14" length, $8000. Recoil pad, 13" stock, $5500.
