Reserve your Proof of Sats card

Series 1 officially launches on September 15, 2026. Until then, you can choose your card in advance and reserve your preferred number while it is still available.

Series 1 celebrates the origins of Bitcoin through 100 individually numbered cards, each containing a satoshi from the oldest bitcoin still in circulation.

Every Series 1 Proof of Sats card contains a satoshi from the first bitcoin of the Block 9 reward, mined by Satoshi Nakamoto on January 9, 2009, just a few days after the Bitcoin network launched.

Each card has its own serial number and a unique guilloché pattern generated from its satoshi number.

Browse all 100 cards in the collection, choose your preferred number, then contact us to reserve it.
