Which grading company should you use? If you're this kmize person, here's your checklist
1) you have T206's
2) they're "high-grade" cards
3) you sell those cards on eBay
4) you need to post on this forum over and over again
If you meet these criteria, then you should use PSA. If you insist on submitting to SGC, then you should read this informative thread that he created:
SGC T206s....It needs to be brought up, it's scary, very scary if you are a collector.
For "collector", read "card flipper". For "scary", read: "not scary". After that, you're on your own.
