A Message From Hank Green

There are just a few days left to get your coin, and some of them will sell out. So head on over to https://complexly.info/CCcoin26-18 to support Crash Course and get our limited-edition coins! Each year we release limited-release coins that allow you to help us reach thousands of learners. For example, every hundred dollar coin helps us reach 2,000 learners. And every $500 coin helps us reach 10,000 learners. We’re also offering coins that help us reach 20,000, 100,000, and (for the first time ever) 200,000 learners! This year, the coin is inspired by our goal to be a signal in the noise. It shows a soundwave that, for us, represents our commitment to offering clarity, context, and meaning. And actually, features the soundwave of the words “knowledge weighs nothing,” which is part of a phrase we’ve printed on every Crash Course coin to date. “Knowledge weighs nothing: carry all you can.” These beautiful objects are minted in Arkansas from hand-engraved dies at Shire Post Mint. And they are only available for a limited time!
