I may be wrong on this but I focus on the vintage items because the modern replicas look virtually identical to the game-worn items. So from a display standpoint, there's not much difference. Say you have a Peyton Manning gamer and I have an authentic replica purchased on NFL.com for $275. Or Sydney Crosby's 2008 opening-day jersey from Stockholm which is on ebay for $10K, compared to dozens of replicas also on ebay. Put them both in a frame inside a sports bar and you'd have to get pretty close to tell any difference between the gamer and the store-bought. I think the vintage items will hold up a bit better in the long-term.
