a simple question really...not an april fools day question, yet.

As we all know, the new issue Washington dollar had a sizeable number of error coins produced without edge lettering. i had heard the figure 30,000 may have been introduced to circulation. my question is this; will ngc recognize this as separate from the correctly minted dollars, or simply ignore them? so far there seems to be no place for them in the presidential dollar set. i don't collect buffalo nickels, but i'll bet there are 2 different coins for 1937d, 4 legged or 3 legged and that seems like the same situation here....lastly, will ngc make a one-per-date set with the presidents???
