I JUST sold a note almost exactly like this. L 0000 0304 *. Different date and run, but it was also a 640k run. It had a fairly visible diagonal fold going from top to bottom just left of the portrait, and it went for $29. I was shocked, I thought I'd get 10 bucks. So that's a good place to start as far as valuing it. Yours looks like it's prettier than mine, so you might get more, who knows.
