jpbone, since this old thread got resurrected from the dead, out of curiosity, what is your opinion on the area of roughness by the date and star 12?
I've put it under my microscope since this was posted, and it appears to be pitting or porosity. I am not quite sure what would have happened; my working theory is that there were impurities or contamination in the planchet in those areas, and those resulted in the pitting seen on the coin.
I might have this one slabbed eventually, and maybe they'll be able to shed more light on the exact nature of the damage, and whether it was a planchet issue, or some sort of highly localized environmental damage.
