Well no shit theyre cheap compared to big names like Urza's block. Fuck those were $500+ sealed when I was in high school.
I cant believe the price of Coldsnap boxes... fuck man my cousin was a judge back in the day. She was usually a cunt about it but right around the time Coldsnap came out she did a whole weekend of judging for which they gave her 2 sealed boxes as payment for whatever reason. She didnt like the set and sold them to my dad for $50ea to give to me for my birthday or christmas or whatever that year.
And yeah. Those sets were great. I really liked Mirrodin too, even though it started the downfall of the game imo.
