Description
The coins in this series have several
unique aspects. Instead of having a
hologram sticker that is peeled off to
access the private key, the holograms
on these coins are ‘scratch off’
surfaces. Upon being scratched (by
perhaps, another coin), a QR code
and written version of the private key
is revealed. Due to the surface being
prone to scratch when in contact
with any hard object, these coins
should be kept in a proper air-tight
holder.
An interesting fact about the ‘1/2
BTC’ coin is that its value is marked
as a fraction instead of a decimal like
all other coins of that denomination.
