Well, at least that's my anecdotal take on it. I actually have hard statistics to back it up. I'm a long-time member on this board, but only a recent lurker. And as a pinball machine owner, I think that my opinion is a little more objective than most people here who don't own lots of machines and obviously have fought against their meteoric rise in value.
All of the previously high-flying, big dollar machines are taking MUCH, MUCH shorter to sell at prices that they would have never sold at just months earlier. They're often even moving when the sellers raise their prices due to bidding wars. They are flying. A lot of posters here have claimed in the past that the pin market surges near Christmas. That has obviously happened. In fact, maybe the Christmas season has simply increased the market further.
I know that I'll be accused of a "troll post" by some. That's okay though. There are always "troll post" accusations from those who deem that a post doesn't jive with their preconceived agenda. This is simply the way I see it. That's all.
