2003 ADV Half Decks

Have come into possession of 3 sealed ADV 1st edition half decks (Mudkip, Treecko and Torchic) and have been struggling to find any information on their value. There are a few unlimited Mudkip sealed decks on ebay for $220-300 but I am unsure if the 1st edition affects the price as I know that some of the unlimited Japanese cards of that era are rarer than the 1st editions.
