Collectibles are not investments. Critical Role is not a publicly-traded company. Do not invest in Critical Role.
That said, here is how much some people have made by flipping Critical Role collectibles.
Talking points include: McFarlane Toys vs. Sideshow Collectibles, the Mollymauk Tealeaf limited edition figure, the Shaun Gilmore limited edition figure, the Legend of Vox Machina Kickstarter backer rewards, the Critical Role Tarot Set, the Chronicles of Exandria, and the first-ever piece of Critical Role merch.
