How many copies did Pokémon Gold and Silver sell worldwide, according to reported franchise figures?

Pokémon Gold and Silver sold more than 23 million copies worldwide.

The pair were released for the Game Boy Color and became the first Pokémon games of Generation II. Their commercial success continued the momentum established by the original Game Boy titles and helped turn Pokémon into a major multimedia franchise.

Gold and Silver added 100 new species, the Johto region, Pokémon breeding, held items, and a real-time clock. They also connected to the first-generation games, allowing players to trade and battle across generations with compatible hardware.

The sales figure refers to the two games together, not to one individual version. Pokémon Crystal, the enhanced third game in Generation II, is counted separately. Later remakes, Pokémon HeartGold and SoulSilver, are also separate releases.
