sorry for the gap in posts. Was away for a bit. Back in NY and dealing with the crappy weather again.

Sky City Darwin Austrailia....minor variation. Both chips have edgemarks at 3,6, 9 and 12 o'clock. The edgemarks read $5 or promotional. One chip has the $5 at 3 and 9 o'clock and "promotional" at 6 and 12 o'clock. The other chip is the opposite, "promotional" at 3 & 9 and "$5" at 6 & 12. Also, the $5 on the front locks different on the chip on the left unless it's just a poor stamp job. Not sure though.
