About the Set
The set follows Jungle’s structure exactly — 16 commons, 16 uncommons and 16 holo rares — and adds the Mysterious Fossil Trainer card. It also contains a holo Mew, which the English Fossil set does not have.
The English counterpart is Fossil, released October 10, 1999 with 62 cards.
How These Cards Are Numbered
Cards from this era carry no collector number. The number printed at the bottom right of the card is the Pokédex number of the Pokémon — the 25th card of Expansion Pack is Staryu, and it reads No. 120. Trainer and Energy cards have no number at all.
What the gallery shows: each tile is numbered by its position in the set (#1 to #48), which is the order the set is catalogued in, not a number printed on the card. Open a card and the lightbox gives both the position and the Pokédex number the card actually prints.
Rarity is shown on the card face instead, as a small symbol next to the Pokédex number: a circle for common, a diamond for uncommon and a star for rare.

Collecting & Where to Buy
Mystery of the Fossils tracks Jungle closely on price. Mew, Dragonite, Gengar and Aerodactyl are the holo rares that draw the most attention.
Collector tip: The card lists are not interchangeable with the English Fossil set: this set has Mew at number 33, and English Fossil has no Mew at all.
