Tom, What I have for trade is in my tradelist.
I collect Posey and don't have any extras on the Colored Refractors.
Regarding these additional silvers you picked up, no one there jumping out at me for more than $1 per card.
You might be right about the Green border blank backs. They're not selling like they are 1/1s, though the Gretzky sold for $175. I didn't see any duplication on them in the completed listings on ebay though so maybe they are 1/1s.
A lot of collectors steer clear of Upper Deck because they are not licensed and they did some unethical things in the past.
I like certain aspects of Goodwin. I really liked the 09 release, but 2011 and 2012 are interesting to me in that they're creative about not using images with team logos and they have some names that don't show up anywhere else. For instance, this year they include Shoeliess Joe Jackson in the checklist...and Billy Beane, and of course, Jordan, Gretzky and Woods.
