The ‘Unchained’ coins were
made with four other metallic
compositions in addition to silver.
The most common of these is
copper, of which 480 are serialized
and 20 have ‘non-serial identifiers’.
Similarly, 20 of the 120 ‘Merlin
Gold’ coins are un-serialized. The
Merlin Gold coins were never sold
directly by Cryptolator, but rather
exclusively via another member
of the Bitcointalk.org forum who
acted as a US distributor who had
some of the lower numbers graded
prior to sale. The Antique Copper
coin pictured on the next page is
the only specimen in which the
hologram is significantly crooked.
