|Recently sold on ebay for £156 (roughly $240). I have a prototype looking exactly like this one, the same label, and it's a final magazine review copy.|
This one however contained a secret underneath the "2" mark on the label. This was actually a very early version of Glover 2 none the less... What a steal by the Ebay winner, congrats! :-)
UPDATE: The cart was recently resold on ebay for $200. The rom has now been dumped as well.
