Erik, I'm not following your point. You quoted Scot Reader's description of when the Sweet Cap 350-460 Series was printed, but the card in your post is from the 350 Series, which was printed earlier.
So yes, it seems that the card could have been stamped on the day it was acquired... or on any day thereafter.
I think that was what you were asking, but if I missed your point, well, sorry.
