Kialara Artist Proofs
Kialara made 12 Artist Proofs while testing different suppliers for parts for what would eventually become the Kialara 2014 Original 0.1BTC. They were numbered AP1 to AP12.
Most of these were never released or seen publicly. One (AP7) was given to a bitcointalk member who bought some Casascius coins from Kialara that helped fund the creation of the original Kialara pieces.
