One day in the early 1970's I was in a gunshop in Lexington KY that I frequented on a regular basis.
In walks a well dressed elderly lady with a prewar Colt Police Positive that was in the box, mint and had mother of pearl grips that had the masonic emblem inlaid in gold. She said "This was my deceased husband's revolver and I don't want to keep it around so I'm going to donate it to my church's charity auction. Could you please give me a value so I can deduct the donation on my taxes." The owner of the shop said " I'd be happy to; these guns sell for about $35.00. If I can make a suggestion, I'll give you $35.00 & you can give the money to your church & you won't have to worry about transporting that revolver" which the lady accepted.
Some people have absolutely no shame when it comes to dealing with the uninformed.
