natsb88, try the Australian Lunar Dollar series. I collect the dragons.
The Dragons are definitely very cool--but they also seem to have a much higher premium on ebay--have you found that you have to pay much more for them--or are you able to be patient and get good deals?
I actually was able to pick up an MS-70 NGC lunar rabbit for about $30 (normally go for around $70 or so) because it was not listed very well.
