The act of trading in any collectible that is graded, vacuum sealed in a lucite case or comes with a Certificate of Authenticity. i.e. Sports cards, comic books, toys, NASCAR commemorative plates, Civil War themed Chess sets, Beanie Babies, anything with the words "Star" and "Wars"...
The value of these items can rise and fall on a whim, but in the end they have no
true value, despite what your monthly
Beckett or
Wizard guides may lead you to believe.
