[esd10]

I had been looking at turkey red cards and it seems to me that a card that's a sgc10 and a sgc30 look to be the same condition but have different grades does anyone know why?i had pulled them up sided by side and they should be the same grades. Is the reason why is the card in question a tougher card to get in a good grade if that's the reason they should say condition sensitive. Can you ask just to have your card authenticated and not have a grade? and if so can you send in a auth and get a grade given to it?
