Valuable items are items that exist solely to be sold for points. They can be found randomly on the site, in the Underground, or in the Prize Shop, where one is rotated every 12 hours; this latter availability allows users to convert their Prize Points into regular Shop Points. Two Achievements are unlocked by obtaining valuable items: Gold Digger by obtaining five Nuggets, and Mycologist by obtaining five TinyMushrooms.
