While the range might be wide, these are all the recorded sales I could find. 1.1 and 3.4 are Outliers for obvious reasons, so 1.6-2.2 should do.

Regarding the gifted australium eyelander? There's no real additional sales for this besides this one, so I'll just go with the normal range for the Aussie Eyelander. And I don't think gifted tags are a curse on post-exploit items.

Additional Proof/Counter-Proof/Constructive Criticism/Feedback is always appreciated.
