Editing Trading card (section)

===Scarcity===
While vintage cards are truly a scarce commodity, modern-day manufacturers have to artificially add value to their products in order to make them scarce. This is accomplished by including serial-numbered parallel sets, cards with game-worn memorabilia and more. Time can also make cards more scarce due to the fact that cards may be lost or destroyed.<ref name=honuswag />

Some singles have been [[autograph]]ed by someone related to the card. The person who autographed the card may be depicted, or their artwork is visible on the card. Cards may also be autographed by the card designer or by a person famous for using that card. The value of an autographed card has been debated, often depending on who has autographed it or the scarcity of the autograph. In some cases, an autograph can be seen as damage to the card, or [[graffiti]].<ref name="OWENS"/><ref name="MILLER2">{{Citation |last=Miller |first=John Jackson |title=Scrye Collectible Card Game Checklist & Price Guide, Second Edition | year=2003 |page=48 |postscript=.}}</ref>
