They weigh about 1.98 grams. Finally, the Holofoil cards weigh close to the same around as the Ultrarare cards, weighing in at 1.93 grams. The extra décor on these cards makes a difference and the proof is in the weights.

Pratte says that in his experience, the Fossil cards have been more difficult to uncover in flawless form than the Jungle cards. With the surge in demand for Pokémon cards from the first generation, we've seen drastic increases in the market value of these cards. This set has been out of print since 1999, and considering how rare the 1st Edition cards are, the future looks bright for this issue." The release of the Fossil Set also completed the release of the first 150 Pokémon into trading card format, in Japan of course they got Mew, so for them it was the first 151. The first three sets totalled 158 actual Pokémon cards (Base Set, Jungle and Fossil) this covered all 150 Pokemon as mentioned, and of course means a couple were replicated, these were; Gastly, Haunter, Magmar, Magneton, Raichu and Zapdos who were all in both the Base Set and Fossil and of course Pikachu and Electrode who appear in both the Base and Jungle sets. Fossil was the final expansion to use the Galaxy Star Holofoil. Although the holographic pattern was changed to cosmos in the Base 2 release, cosmos holographic cards have been sighted. I would say that the 1st Edition Fossil cards were much more accessible than Base [cards] and probably [were distributed in quantities] on par with Jungle," said Pratte.Fossil is the name given to the third main expansion of the Pokémon Trading Card Game. In Japan, it was released as Mystery of the Fossils, the third expansion in the Pokémon Card Game. It is based on Pokémon Red, Blue, and Green, featuring Generation I Pokémon and Fossil Pokémon. The English expansion was released on October 10, 1999, while the Japanese expansion was released on June 21, 1997. Subsequently all other language releases for Fossil were April of 2000. In the United States Fossil had originally been planned for release in January, 2000 but due to the original schedules for Jungle being pushed forward Wizards also chose to push forward the release of Fossil, releasing around 3 months earlier than originally planned on October 10th, 1999.

"The 'legendary' term was reserved for the rarest Pokémon and typically the most powerful. In the game, you would encounter Articuno, Moltres, and Zapdos in these caves and you had one opportunity to catch them. They were very difficult to catch. They're legendary in the game; they're very powerful and they're difficult to collect, so people have a higher appreciation for them." Pratte believes that 1st Edition Fossil cards were distributed more widely than 1st Edition Base. He even remembers having a few 1st Edition Fossil cards as a kid.

The PRERELEASE stamp on the card that can be found in the lower right of the illustration box, can be either brown or gold. Cosmos holo Zapdos A Cosmos holofoil Zapdsos 15/62 from the Thunderstorm Gift BoxI think one of the factors [driving this set's popularity] is that guys like me, who have grown up collecting these cards, have become self-dependent [over the last two decades]. They have jobs now and some extra [spending] money, so I believe they probably just started buying cards for fun and then they realized that these cards are hard to find, so that's when it became a hobby for them," said Blaney. "It seems like a lot more people have entered the hobby and it's made the prices go up because these [1999 Fossil 1st Edition] cards are getting more and more scarce."
