I'd imagine it might go for less as more people find it during the event. but once it is sparse it may be worth it to hold off selling in hopes of an inflated value in the near future. thoughts?
You also have to take into account all the people who are thinking the exact same thing. Most of the people playing right now that have a lot of gold have the masks already but it could be possible to sell it to those who are late to the game next year.
