I had recently picked up an SGC40 T206 Magee (Portrait) in a lot and was excited when I saw one sell on eBay last week (11/21) for $130:

Then Sunday (11/27) another one sold for $121 (with shipping):

And wouldn't you know it, a third sold last night (11/28) for a paltry $81:

I say this somewhat jokingly... but in one week the "market price" for SGC40 Magee Portraits dropped nearly 40%!
In my opinion the Probstein card was the nicest, but the auction only had a scan of the front of the slab. The Broadhurst card appears to have a crease (upper left), yet yielded the best price. The PWCC listing has nice large scans of the front and back, appears crease-free, but has significant rounding of the corners.
A few questions...
Is a crease more acceptable than rounded corners?
Does the lack of a back scan leave money on the table?
