Would anyone happen to know a fast/good/easy way to get coins?

Try looking here: http://beastkeeper.com/thread/3358

Another way is to  browse through the trading areas (Brreding, Pet, and Items) and see which cost the most, then try getting them for cheap and reselling. (If I remember correctly, that was how I started getting silver, by buying and selling magic bombs, though then they costed around 3 times what they cost now.)

Thank you!
