I envy you American folk. You can go to a card show and pick up relics and autographs of scrubs for $1-2. Not here. The cheapest tend to be found around $10, though their book value from (now defunct) SCM lists them at $25-30 to start. Yup, that no-named scrub who plays on the farm team and carries a triple-digit jersey number books at $30. Then again, autographed card print runs rarely exceed 100, and are usually around 60 each.
But seek and ye shall find. One of the local card shops here occasionally throws some nobodies into a clearance tray at 500 yen (about $5) each and if I see them I pick up the ones I need for my type collection. Nothing really special here, but let's see what my latest splurge got me:
Getting an autograph from one of the box sets is a pleasant surprise since overall there tend to be fewer; the average team set release probably has 4000-4500 autographs, while the box sets have 3000 or less (usually 1000-1500, I think). Really, getting to knock any of these cards off the want list is always a big plus in my book! Next year, I might focus more on my Japanese type collection, especially increasing the number of autographs I have.
