Description
In addition to the scratch-off hologram (pictured
above in action), these coins contain another unique
security feature. Each has a gold-tone security sticker
around the hologram, which serves several purposes
from preventing the removal and replacement of
the hologram to preventing the coin from being accidentally scratched in the process of
scratching off the hologram. It of course also serves as a visual feature, bearing images of the
logo. This is the only physical Bitcoin made in the denomination of three.
