This glitch only works in the English version of Gold/Silver. It does not work in Crystal. According to: https://glitchcity.info/wiki/Coin_Cas...

To perform the glitch:

PREPARATION

-Put the listed items in your PC in the exact order and quantities.
-Get a Quagsire holding HP Up with Sleep Talk as its first move in your 4th party slot
-Some low-level freshly caught Pokemon in your 3rd slot. If the glitch doesn't work try some different Pokemon.
-Any Pokemon in your first party slot. This will become Celebi. Move sets and shininess transfer to the Celebi.

EXECUTION

-Save and reboot the game just inside Professor Elm's lab
-Walk down (through Elm's lab door to the outside) and 4 spaces right
-Listen to Machop's cry in the Pokedex
-Access your coin case, making sure to change bag pockets at least once
-Fly to Goldenrod
-Go to the daycare and give your first Pokemon to the lady.
-Take the Pokemon back and it will be a Celebi!

-To get the Celebi entry in your Pokedex trade the Celebi to another game cartridge and back to the original.
