1. If you use the list = 3-4 '09 rares
2. If you use the list = 6-7 '09 rares + '09 uncommon
3. If you use the list = 6-7 '09 rares + '09 uncommon
4. 3 month rule
The Rare's List has been discontinued, so if you don't use the list, I've seen people value 2008 very rares (the Blue Scarf Dog) at 2 '09 rares + '10 rare or 4 '09 rares
Without the list those bunnies would only be worth 2 '09 rares for being released in 2009, and I personally only value them that much. However, it's completely up to you how you personally value these pets. You could value them at their list value or by year, it doesn't matter. Some of these may go for more demand wise but how much they go for depends on who you trade as not everyone values a certain pet the same. c:
