I like it. However, you need to tweak the drop list. For one thing, it's the 'bone' demon, shouldn't he drop some bones? Possibly a 100% drop could be 5 Big Bones. The other thing is that members would take advantage of this. They could solo the demon fairly easily, and if it drops 5-10k each kill, well, they'd get rich way too easily. Possibly make the coins a non-100% drop.
