Is the obverse a doubled die also? I think it's coppercoins 002. It could be 001 though, it the obv. Is a DDO. Check the markers for 002 first. http://www.coppercoins.com/lincoln/diestate.php?date=2004&die_id=2004p1dr002&die_state=mds
I've been looking for either one so congrats! It feels like I've looked at a million 2004s. None of the 2 majors yet.
