Start with the 2016 Year of the Monkey and continue each year going forward. This gives a good opportunity for early collectors of the series to see profits as new collectors each year drive up the premiums on previous years as they try to collect a full set. This is also seen with Chinese Pandas.
Design competition for a new specific MicroSoul hologram sounds cool, I would try my hand at it just for fun. I think it would be neat to incorporate Chinese symbols into it, maybe a rough Chinese translation of MicroSoul if it's only for the MicroSoul Lunar Series coins.
As far as what design to make first- I would try to stick to the current year's Lunar animals. Like for 2015 I believe is the Year of the Goat for the Perth Mint and other's silver bullion coins (I could be wrong, I follow coins and silver but not the various Lunar coins). I think you'd have better luck with your goal of them selling to "non-Bitcoin" people if the year and animal matched up with the current year's Lunar animals on other Silver coins. I would really try to play on the low mintage aspect then as well. I will post it to reddit.com/r/Silverbugs for you when you know a production date or something. Big US/worldwide silver and coin community there.
