Not to be
I can't claim they'll be valuable collectibles someday, but they do strike me as something that will be interesting mementos of a dark time in spaceflight history. The Space Store still has for sale mission patches for Expedition 7 and STS-114. It now appears that what will be Expedition 7 will consist of two members (at least one from the original Exp. 7 crew), so at least the names on this patch, if not the whole thing, will likely change. Likewise, STS-114 was to return Exp. 6 to Earth and carry Exp. 7 to the station, meaning that, at a minimum, 6 of the 10 names on this patch will change.
Every once and a while, you see a patch on eBay for one of the planned post-Challenger missions that never happened. That said, though, the patch that I most want, but don't know if it was even ever produced, was the original Soyuz TMA-1 patch from last October. The final patch ended up being similar, but just not the same.
