For $5,000, you can help us reach 100,000 learners and receive a premium 1.25” titanium coin minted by Shire Post Mint in the US. Each coin features a unique hand-stamped number, and comes with a thank-you card signed by John and Hank Green.

The front features our signature image — a door being opened to our knowable world. All one needs to enter is curiosity. The door is surrounded by 200 hash marks, each of which represents 500 people you are helping educate. The back features the soundwave of the words “knowledge weighs nothing,” designed by our in-house graphic designer Elliott Zheng. This art represents our commitment to offering clarity, context, and meaning in order to be a signal in the noise.

Each 100,000 learner coin comes in a small wooden box.
