I saw the humor, and agree that many of the errors could just as well be seen as flaws and lower the value.

Here's one I picked up, when Excalibur first had they Silver Strike machines. I didn't even notice until I got home, or I would have returned it.

Maybe now it's a "valuable" error token? lol If the image doesn't show it well, the center, which should be silver, has overspray of gold coloring from the rim, covering most of it.
