Hmmm... someone said it used to be 8.0 but doesn't say how they know, and someone else says it was pressed, but also doesn't say how they know.
I had another look on the ebay listing to see if I missed it being mentioned but still couldn't see anything.
Those two people appear to have significant history on that site, so maybe they are just referring to something that only hardcore comic collectors know about... kinda like hardcore collectors of Transformers have an idea of who owns the rarest Transformers (like those Gen2 Stunticons).
