Description
English: Photos shows pile of 1BTC-denominated brass coins, with the bitcoin logo, production year, the text "Vires In Numeris", with the tamper-evident holographic sticker on the reverse. Printed on the sticker is a portion of the digital coins' public address, for verification of the coin's value. Beneath the holographic sticker lies a private cryptographic key, used to redeem the coin's value, and move the bitcoins contained by the coin into the owner's private wallet. Removing the holographic sticker leaves a hexagon pattern, and indicates to any future owners that the digital Bitcoin originally loaded on the coin have likely been removed.
