Nice screen shot, I didn't know those beans were still around either actually... it's amazing how much we miss now that everyone medals up and lvl's or does certain quests to lvl now. We miss so much of rose, that we all used to once play in constantly. Brings back memory's Ah good times.
The ones at the Golem area give about 230k each. I think they made the beans really low level so the overkill exp was almost non-existent anymore, so it's just an exp boost, not half a level.
