Back in 1988, I sold a vintage Gibson, Charlie Christian model (lefty). I had no idea of the value. I got 400 dollars for it. Thinking I made out well sinec it was old and really used. Three weeks later while walking down 48 street in NYC, which is the music center, I saw the same guitar in the window of a used guitar store selling for $3000. That was the biggest, dumnest, or what ever you want to call it mistake I ever made.
Mine was a left handed model, so add about 20% to the $3000 grand for the right handed model.
Live and learn.
