Is pinball pricing seasonal? I understand that prices for desirable 90s machines have been climbing pretty steadily for the past decade or so, but what I'd like to know is if pricing is seasonal. By that, I mean is there a fluctuation in price between Spring and Fall, like with convertibles, or do prices tend to spike before Christmas and then crash afterwards.
Looking for opinions from the "seasoned" collectors with more experience than me (any experience...).
