I don't think you have to worry about any knowledgeable Bears collector bidding let alone driving up the price on this supposed Urlacher gamer.
Funny thing about this jersey is that it sold a couple of months back for $400 as issued by another seller on eBay and now its become game used with this seller
No visible wear and it looks like the jersey has been washed multiple times from the number puckering. As far as I know Urlacher only wears his game jersey's 1-game unless its an alternate jersey that being worn twice in a given season so how is it that the numbers are puckered???
I have 4 Ulacher's in my collection and ALL show wear.
This thing is a Turd & I would Avoid
