Re-built or not the fact is the Plank is a great looking card.
And if a collector want's a 150 series Plank which will always have a better image he hasn't had much choice in un-altered copies.
The last 4 out of 5 150's for sale I know of have all been altered.
PSA 7 Copeland Plank "Harris Collection" known trimmed card.
AUTH Wagner-Mate Plank REA "Trimmed"
(One of only a few P150 cards, the only one that isn't in poor cond or missing colors...the others were part of the Halper collection, it's also connected to hobby's most valuable card)
AUTH FrankenPlank SGC Huggins Scott Rebuilt background and corners and color added. (Has sold several times in both raw, PSA and SGC for around 15-24k)
AUTH PLank in REA now Re-built Corners
Just are not that many 150's floating around 350's come up way more. That could be because they are tougher or that folks keep the better looking and sell the fuzzy 350's....
As far as what it will fetch I guess we will find out..as a bidder I wouldn't pay twice as much as the market set less than 60 days ago. No matter what auction house was re-listing it.
Cheers,
John
