9. Tropical Mega Battle – Tropical Wind – PROMO card
Many of the most valuable Pokémon cards are promo releases hailing from tournaments or special events. This particular trophy card was given to players during the invite-only Tropical Mega Battle held in Hawaii back in 1999. The competition saw players from around the world entering the fray. (As rules changed, the annual event was renamed in 2001, becoming the Japanese World Championship) While the card is rare, mechanically, it’s a fairly basic trainer card, forcing players to flip a coin to determine the outcome of an event. According to PWCC, very few of these Tropical trophy cards exist on the open market and almost none are as pristine as this PSA-rated GEM MINT 10 version that sold at auction for just over $65k.
