What area are you from that ASM 361 was a $1 and ASM 129 was $25, I was collecting and attending plenty of cons in that 2001-2008 range I remember the 361 dropping to 10$ - 15$ on like 2/20 deals but never even to $5 regularly. And ASM 129 was never under $75-$100 during that era in my memory. Again that is in the NJ,NY,Philly, Baltimore con area so it could be regional.
One caveat, you can hit on anything in a random dollar box, I have had some great scores over the years from BA 12 to ASM 252 to FF 112 but I would never say those were 1$ or 2$ books.
