O-107 R2 below, O-107a R2 at bottom

On my list of toughest R2's. Perhaps most were circulated, but higher grade examples, though available, do not appear as frequently as one would expect. 23 AU/MS examples have appeared the past 10 years, which is not a lot considering that R2 indicates 500-1000 examples xtant.
