Quoted from mbwalker:
Adding to this comment: How about having a local Pinsider (to the seller) go to examine a pin for a long distance buyer? Maybe verify the PF condition, confirms it plays, switch/light test, etc. Take any pictures the buyer requests.
While this would be a great idea, real world not so much. If you’re not the guy with the money, why deal with them? Pictures would be fine or even a video. Of course having folks come over to play would be horrifying!
