Pokemon: The Movie 2000 (a.k.a. “The Power of One”) was released in North American theaters on July 21st, 2000. It was the translated version of Revelation Lugia.
North American audiences never received an equivalent to the promotional pamphlet. Instead, the card was inserted in a cellophane packet with a teaser card (teaser cards are cards intended to cover the fronts of trading cards to shield their identity until the cellophane package was opened). Other countries had similar promotions in their country, the packet containing an Ancient Mew with their own teaser card printed in the native language (e.g. Norwegian, Swedish, Finnish, German, French, etc). The English version and the International version have the same Ancient Mew, and are considered to have the same price value – unless it is sealed with the foreign language teaser card. In this circumstance, they are valued at approximately US $10 - $20.
This one you have is the North American version, you can tell from the print at the bottom of the card and the way the front of the card is. The japanese version is quite a bit different!!
Still a pretty awesome card, since the only people who originally got them were ones who went to see the movie the first week it came out!!
