The last update on this thread is over 2 years old. There have been a few more of these graded and a set of 1/10 and 1/20 showed up in the recent auction in Macau.

The last update in 2013 originally had 4, 1/10 graded. Of those 4, three were mislabeled. Leaving one original. Today there are 6 in total graded by NGC. Two of the originals are still mislabeled - 3593098-004, 009 (the other was fixed by NGC). Therefore there are now a total of 4 in the NGC population. Two of which are known.
