Joe D.is to talk to SGC in person. Especially if you can visit them.
A few times (I think 3 times total) I told SGC that I disagreed with a grade.... and they gave it due diligence with the graders and came back with their reasoning for the grade.
I did have success once with getting it upped a grade as they agreed it deserved the higher grade.
This was after I paid for the slabbing - so I don't know if there is a 'check the grade' fee in your case, but for me it was free.
I'm not sure you would have such a high-percentage chance on the upgrade....
but you wouldn't have to ship it, or crack it out, or have it leave your hands -
possibly wouldn't have to pay a dime...
and you could possibly walk away with an upgrade... or at the very least hear their viewpoint on why it received that grade.
edit to say: I type slowly, but it looks like T206 and I had similar thoughts.
