I appreciate your query, but I need to clarify that the search results provided don’t contain information about shadowless Pokemon cards with 2000 copyright dates or any medical content. The search results discuss shadowless cards from the original 1999 Base Set printing and mention the Masaki promotional cards, but they don’t address copyright dating or medical-related information.
Based on what I can tell you from general knowledge about Pokemon trading cards: Shadowless cards were printed in 1999 as part of the first print run of the Base Set. These cards are characterized by the absence of a shadow effect behind the Pokemon illustration. The copyright date on shadowless cards typically reads 1996 or 1999, depending on the specific card and printing. A shadowless card with a 2000 copyright date would be unusual and potentially suspicious, as the shadowless print run ended before 2000. Cards printed in 2000 would typically have the shadow effect and would be from later print runs.
If you’re trying to authenticate a shadowless card you own or are considering purchasing, the copyright date is one of several factors collectors examine. Other authentication markers include the presence or absence of the shadow, the font style, the card stock quality, and the overall print quality. Shadowless first edition cards in mint condition can be quite valuable, particularly rare ones like Charizard or Alakazam.
However, I cannot provide the extensive article you requested because the search results don’t contain the specific information about 2000 copyright dates on shadowless cards, and there is no medical information in the search results to cite from authoritative sources. If you have a different question about Pokemon card authentication or shadowless cards specifically, I’d be happy to help with that instead.
