Hey Shep,
Congrats on the copy of SSWS 6. Because Pedrin's guide listed that book as "extremely rare", I bought every copy I ever stumbled upon, unless the price was ridiculous. I ended up with 7 copies.
I did the same with G. I. Combat #87, and I ended up with 21 copies. I did the same with SSWS 151 and I ended up with about 35 copies.
Is SSWS 6 "extremely rare"? I doubt it. Tough to find? Yes. I don't have a copy anymore and I other than my last copy that I sold in 2010, I don't think I've seen another one in 2010 or 2011 so far. It is tough.

It's extremely rare because no child could get past the ridiculous cover!
Shep, you'll always be sheep to us now.
