The owner making a list with values only helps so much as many people think theor stuff is worth more than it actually is. And then a widow may be stuck on getting the money shown on the list. And if the values are unrealistic, things will not sell.

What really is best is for clear insteuctions to be left as to how things shoukd be disposed of. ie: through a dealer, gun shop, auction house or friend that the owner knows and trusts.
