We posted an article back by the comics indicating how much condition can affect comic, and by extension card, prices. In addition, media attention drives pricing as well. For example, a copy of Iron Man #1 in near mint condition, graded at 9.6 or 9.8, sold a decade ago for about $3000. Today, thanks to the success of the Marvel movies, the same book sells for around $18000. However, an average quality copy, graded at about a 5 or 6, sells for only about $300.
