Never saw one with a green stain; very cool.
Prices on these are all over the place. It really depends on who is surfing eBay on any given day/week. I watched one go for a little more than $400; really regretted not getting in on that one. Then, another, in the following days, was driven up to over $800. Two bidders were cutting each other, terribly. The less expensive of the two was a "script" cue, while the more expensive was an "originals". That could be the reason for the difference. Either way, "originals" or "script", it's a pretty rare Moochie.
