There is no way of catching Mew without a Game Shark in Pokémon Silver, Gold and Crystal.
Alternatively, however, you can obtain a Mew in Pokemon Red, Blue, and Yellow versions. I won't go into how to do that here, though, as there are several websites that have this information (try YouTube for visual info). This is caused by a glitch, and is legit (technically). You can then trade it to Pokemon Gold, Silver, and/or Crystal.
