1948 Kellogs Pep Bob Waterfield - question
 

Hello guys,
I am more of a memoribilia collector, but picked up this card in a lot, and no nothing of the set. I am going to try to sell it at some point, but my question is, should I get it graded? What kind of value do cards of this set have?

Here are a couple of photos, the tape is not on the card but on the plastic holder.
