My best friend growing up was a manager at a Sherman Clay Organs and Pianos store on the west coast (and top salesman three years in a row Nationwide - yes, he was over the top annoying - lol!).
Back in 1987 he got a call from a lady whose husband had passed away. She wanted him to come take an organ he had kept covered in one room of the house. She was willing to give my friend $200 if he would just take it away. She hated the thing with a passion because her husband seemed to pay it more attention to it than her. My friend pulls the cover back to see an immaculate B3 and just about falls over. "This could be worth a lot of money!" my friend tells her and she replies "I don't care if it's worth a million, I hate it and I want it out of here!" My friend says "Ok, but I'll give you $500 for it." She was surprised to get anything, but didn't have a clue what it was really worth. He sold it the next month to a Japanese investor for over $29,000. Turns out it had papers inside it proving the Rolling Stones had used it.
Just another reason why I never trust sales people! LOL!
