All-in-all I think Daughter #1 "needed" about 1/4 to 1/3 of these 100 cards (a lot of them were from the Sandstorm set, which she was more complete on than a lot of others), but I'm guessing that were I to figure out the price per card even on those, I'd be in the "ten cents on the dollar" range!
Speaking of pricing on the cards ... I won a few "pig in a poke" (i.e., the seller wasn't specifically listing the cards) auctions from a card/game shop ... they were apparantly clearing out some stock, as all the cards came with price stickers on their sleeves. It was interesting to see actual retail pricing on some cards (since most of my price data comes for on-line vendors) from a brick-and-mortar setting. Their prices for the holo/reverse-holo cards were about a buck lower than my "low site" ($6.99 vs. $8.00) but their rare cards were much higher ($4.99 vs $2/$3), although in one case it was a wash (a revese-holo Jolteon from the fairly rare Skyridge set was marked $7.99 when the low site had it at $8.00) ... again, it's nice to see what I'm figuring on as "street price" is pretty close to what's out there.
