I finally replaced my old 2-In-1 Canon with a CanoScan 9000F (with CCD scanning element). Wow, what a difference! Took me 3 weeks but I re-scanned everything I own and love the results. If you remember the old scans on my site, boy were they blurry! The new scans are really crisp and bright, I don't know why I didn't do this earlier. I also scanned the cards with the lid up for maximum contrast. Highly recommend having a proper scanner, makes all my cards feel new again!

Here's a before (pre CCD) and after (post CCD). It's not pre-war baseball, but I felt this card best illustrates the difference.
