So I had 4 coins in NGC slabs. I sent them ATS for a crossover, because I needed one in the other guy's slab for a registry set there, and they are impossible to find in the wild. Now, all of the coins had a perfect grade. My hope was to obviously get all 4 to cross over, but realistically I would have been happy woith three of the 4, with the plan to sell the other two to recoup some of the cost from the submission.
Well to my surprise, only 1 of the 4 crossed over with a perfect grade. Luckily they did not crack the other three out, so they are still in 70 slabs. But is this surprising? Are they that much more stringent?
FYI, the NGC population for this coin in a 70 is over 10,000. ATS, there are less than 300.
