Predict the grades? $20 for "closest to the pin" guess

[Belfast1933]

Thought I'd try something new (at least new to me... probably done here before).

I have these 9 cards that I may submit to SGC for grade to be able to sell so I can buy more great cards here from fellow Net54 members

If you experts don't mind predict the grade each card will get from SGC and I'll pay whomever gets closest to the most right (or near right) a cool $20 bill... (probably Paypal, F&F)

Totally making up a point system here:

Correct grade = 100 points
Miss by 1/2 grade = 50 points
Miss by 1 grade = 25 points
Miss by more than 1 grade = zippo points

If there is a tie, will ask Leon to pull name out of his favorite baseball hat to pick the big $20 winner.

(speaking of Leon... I hope this is OK! Just thought a little contest with small prize might be fun and helpful. I think the kids call it crowdsourcing, right?)

Please list predicted grade for each card:

51 Bowman Doby
57 Topps Lemon
80 Topps Henderson
60 Topps Kaat
51 Redback Kiner
48 Leaf Kiner
58 Topps AS Musial
93 Topps Jeter
62 Topps Billy Williams

9 cards, 9 guesses... let's see who has the best SGC eye?
