This might be a good test of the extent which "Buy the Card; Not the Grade" exists in the real world. Both cards are offered by the same seller, so that variable should not be a factor.
Two-part question....
1. Which Greenberg will sell for more?
2. Which Greenberg would you rather have (if neither one was slabbed?)
Card "A"...

Card "B"...

I have an idea how this will play out, but am curious to see what others say...
Thanks!
