Ha, ha. That takes me back. I'm finishing my first book about something totally different and in it I tell a story about in my teens (in the Bronze Age, or back when Moses played himself in The Ten Commandments) somehow diffusing a tense racial situation at a dance at Canarsie H.S. by getting up and playing my ca. 1968 George Harrison Telecaster---complete with maple neck and bulbous solder work (fortunately on the back).
I bought that guitar around 1970 for $110 from old friend Bobby Lenti, and held onto it through the '80s----when a dealer at We Buy Guitars on 48th st. said
"I want it"
Meaning, of course, 'name your price (within reason)'
Being the ever-astute businessman I was and am I let it go for $460, asking $500 and blinking before he could get a sentence out probably. He had to get $800-900 for that guitar, minimum.
Oh well, my profit was still more than 3x what I paid. And I've never been attached to guitars......
Well, then, mine must be worth about 10 grand at this point!
Go ahead, rub it in, why don't you.....
