What is everyone's thoughts on crossover grading? Just got back a Max Scherzer rookie card from PSA that's a 9 after sending a bunch of my better cards to SGC at The National last year when they had a special promotion. Thought it made sense to see what the grades come back as at a discount before seeing if it was worth sending to PSA for a more legit evaluation. Did I go about it the right way or should I have just sent everything to PSA first?
