question on a hammer

got a req 8 gold +5en colossal pick, looking for a range, thanks in advance

Well someone valued my R8 15>50 Colossal Pick at minimum 60 ecto a couple of days ago. So taking an educated guess I'd say your +5 energy is worth minimum 30ecto. That based on the fact +5 isn't that great on hammers & also that 15>50 is rarer.
