RE: The ''How much is a card worth?'' topic.
@Psyphoon - That is known as a “blank misprint” card. There are two types of these cards: blank fillers (which were completely blank) and blank misprints (which have borders). The completely blank cards took up any existing empty slots in the last squares of the sheet. They were primarily considered "filler" or "test" cards in the manufacturing process.
Your card is a misprint. Due to its yellow border, it shows that the front was never placed. In rare circumstances, blank cards were accidentally inserted into booster packs after the final cut was made. I have seen a few of these cards between $15 - $50, depending on whether it was white, silver, or holofoil. Blank misprints (holofoil) are in the higher end, roughly $30 - $50.
@mlouden03 - “Square Cut” is a term used to describe cards where the corners weren't rounded (i.e. they are sharp, thus creating a perfectly edged card). Here is a
link or
two to give you an idea of what they look like. The second example (EDIT:
Ninja'd! This is also mentioned by omahanime) compares a regular card to a square cut card.
Sabrina's Abra (Black Star Promo #19) was cut correctly a good ninety-five percent of the time. You have one of the oddly cut cards.
I would estimate it to be worth around $4 - $6, depending on its condition.
While I am on the topic on improperly cut cards...
Printing cut errors are erroneously believed to possess high worth, yet in fact they are worth less than a regular card because they are considered to be flawed. They can be graded, though it will never be a PSA 10, 9, or even 8. This is because one of the several grading requirements for a card is alignment and centering; if the front and/or back of a card is not centered to specific measurements, its grade number is lowered until its measurements match those found in a particular grading category.
