T206 SGC 84 - Is the writing on the slab or the card?

[iwantitiwinit]

I think its on the slab not the card. Look closely at the Unglab reverse, it looks as if other things had been written then erased. I'd bet that whichever dealer owned this card had previously written different prices on the back then erased it and subsequently put different prices on it. Don't know why they'd do that though, probably had to press down pretty hard for that to remain as prominent on the plastic. One thing though that might counter my argument is that the writing looks pretty clear, if it was on plastic it might smear a bit more. Lastly, I was watching these sales and thought they went a little inexpensively for SGC 84's especially Probsteins which tend to go for a bit higher price than usual.
