Wow you dug that one up from a while ago.....yep likely to be a player issue but technically not rarer than an individually numbered card if you think about it.
Was going to post that one, utterly insane price. Its unfortunate the mid 90s cards seem to be going through a huge listing price increase (with not alot of people buying).
20 Albums and Pages 16 x $25 + 2000 Folder $150 / 2001 Folder $75 /2002 Folder $40 / 2008 Centenary $30 = $700 give or take.
20 Common Sets 16 x $25 + 2000 Set $50 / 2001 Set $40 / 2002 Set $40 / 2003 Set $35 = $565 give or take (more take than give)
So he's pretty close to the mark with his starting price but I doubt he'll attract any bids.
