Why the Difference in Bidding Activity?

Riddle me this. Two coins, both 1943-S 67+ CAC. One got all of the love and sold for $125 more than another 67+ CAC coin that sold the prior week and for $147 more than the other 67+ CAC in the same auction.

Here is the one in demand. Lots of hairline scratches and some discoloration on the reverse.

The ignored stepbrother. 12 bids versus 27 bids for the first coin. First coin also had extra pictures so obviously GreatCollections saw something special in it. Why? Let us know your thoughts.
