These ‘AT’ (Artificially Toned) coins are a result of
testing undertaken by Ravenbit. These chemical tests
destroyed the patina of the bronze, leaving interesting
metallic colors on the coins. Though it would be normal
to dispose of such coins, Ravenbit demonstrated
obvious creativity in naming them after planets (this
idea was presumably derived from the colors caused
by the chemicals, reminding the viewer of planets).
Each of these coins is entirely unique and comes with a
standard ‘Gray label’ hologram.
