Found a gem in the AH.... any help on a price check?

Found an ammy in AH that was wayy underpriced.

stats: lvl 62 +19-42 damage 92 int 207 vit 42 lightning res 13 %life 59% crit damage

I've found other ammies with similar stats in the AH goin for 5-10+mill but I haven't seen any with the +damage stat that high also.

Any help is greatly appreciated! thanks!
