Thanks for everyone's replies. Yeah, I wasn't suggesting that the rarity of these two makes them somehow worth massive amounts of money. I was mostly just surprised to find that they both came back as the only graded copies of these two issues. But, obviously, it's a title and a publisher that's way off the beaten path, so it's probably not that surprising.
Mostly, it's just cool to know that (for the moment) I'm the only owner of graded copies of these two books that I really like.
Thanks, guys.
