As seen here there are five Easter eggs - if they are in your inventory together for the first time you'll get the cute Egg Hunter Trophy (but that makes the eggs disappear from your inventory, so get a second set if you wish to keep the eggs themselves as collectibles).
Selling the five eggs as a set.
50k per set (if you buy a second set, that one will be 45k)
