The grey "test printing" is worth a lot more, but this is the first #1 that I have seen listed for a long time that does not have a reserve. That's why I have thrown a couple of bids at it. Kind of kicking myself now for being impulsive.
Noble Knight has some later issues like #8/9 listed for over $30.
Roisin_ruaidh has had one in his eBay store now for a long time listed at $250
I should be saving my "online purchase budget" to snag a copy of Delta Green without the
D20 stats that will be in the new release (which is supposed to be dual stat with BRP).
