Which version do you have?

If you just want the card, grab the Standard version for $5. The 1st Edition ($48) and Shadowless ($14) versions offer significant premium due to their scarcity and early printings. The 1999-2000 version ($9) is a middle ground. Save your money unless you are a serious collector willing to pay a premium for the historical significance of the early printings.
