In my humble opinion the cards are on average in NEAR MINT condition, but please decide for yourself. All cards are sleeved to keep them in this condition.
Pokémon Chrome Trading Card Series 1 was a set of Pokémon-themed trading cards produced by Topps in 2000. It consisted of 78 cards covering the first 78 Pokémon. The artworks on the cards of 1 to 76 were also released in Pokémon Trading Cards series 1 and cards 77 and 78 in Pokémon Trading Cards series 2.
All Starter pokemon are in there: Charizard, Blastoise & Venusaur (Charmander, Charmeleon, Squirtle, Wartortle, Bulbasaur, Ivysaur, Pikachu).
Chrome cards can be easily distinguished by the TOPPS Chrome logo on the front of the card.
Cards from the regular set do not have this logo on the front.
See BULBAPEDIA (Pokemon wikipedia) for information about these TOPPS sets. #9
