AnonymousJim - Please no...thanks.
Ted - Yes the cobb was an obvious based on the card itself. Although I am not a back expert. If ever there was a question regarding front/back combo's I would turn to you, the expert.
No knock against the collector who bought it, we all make mistakes. Hopefully we can prevent them with advanced warning or knowledge but if not we can always learn from it.
It took some time but I dug up the pic I posted of a cleaned slab. This one is a PSA slab that was cracked in two and had the tamper reisistant frost polished off. It was very much frosted at the start. It is time consuming, dirty and arduous work. As you can see it is close enough to fool most IMO. SGC's slab is much easier in all aspects.
