I just heard back from Chris, and he has confirmed that it is an ACSC 8c, or double-print. It is damaged, and repaired, but still becomes the third known copy, and the only non-OS punctured version. I'm awaiting for its arrival, and will post a copy of the cert at that time.
Value in ACSC 2017 catalog for the two known copies with OS puncture is AUS $7500.
