I just received my cards back from SGC that were submitted at the National.
I am reasonably pleased with the results. 20 cards were submitted with some being attempted crossovers, upgrade requests, and good old fashioned grading of raw cards.
I submitted 11 graded cards for crossover of equal or higher grade. 5 came back equal to original grade, 2 are .5 higher, and 4 did not crossover.
2 cards were cracked out of PSA 4.5 cases prior to submission and both came back as 60(5).
4 cards were already graded by SGC and I wanted to try to get half grade bumps. 3 out of 4 were bumped the half grade including my Lindsay, Abel, and Delvecchio.
3 were submitted without any previous grading and I received the grade I expected for 2 and the third was a pleasant surprise at a full grade higher than expected.
