Satchel of Gold
From MHWiki
A Satchel of Gold is recovered from some mice <<have seen a Master of the Cheese Claw and two of the Students drop one so far, more to be confirmed>> while hunting in Furoma. It serves no purpose beyond providing bonus gold to the MouseHunter.
Combat Research comes in values of 750-1250 (possibly?) gold <<have seen instances of 500,750 and 1000 gold so far, more to be confirmed>>.
