30Worth A Lot - Charizard
Printing errors can make the value of a card go up an insane amount, as it makes these cards unlike most.
The value of a Charizard card from the Base Set can vary depending on a few key features. When the cards were first being created, a printing error resulted in some cards being “shadowless.” This refers to the border around the illustration.
A 1st edition, holographic, shadowless, mint condition Charizard from
the Base Set once sold for $11,999. But now, it can be valued at up to $20,000. That is a serious chunk of change.
