In Pokémon FireRed, you get the Coin Case in Celadon City from a man inside the local restaurant, just south of the Game Corner.

Quick Scoop: Where to Get the Coin Case (FireRed)

  • Travel to Celadon City (the city with the big department store and the Game Corner casino).
  • From the Pokémon Center , walk south past the Game Corner until you hit the stone walkway with several buildings.
  • Enter the restaurant (it’s the first small building on the right side of that stone street, not the Pokémon Center or Mart).
  • Inside, go to the back-left corner and talk to the bald, grumpy old man who complains about losing money at the slots.
  • After his dialogue, he’ll give you the Coin Case , letting you finally store coins and play at the Game Corner.

“In the restaurant… a guy fed up with gambling gives you his Coin Case.”

Why You Need It

  • The Coin Case lets you hold coins used in the Celadon Game Corner slot machines.
  • With enough coins, you can trade them for TMs and special Pokémon at the prize counter, so it’s basically your ticket to some powerful rewards.

Tiny Misleading Guides to Ignore

Some modern blog posts wrongly say you get the Coin Case from a clerk or a woman in the Department Store or near the Game Corner entrance; that’s not how it works in the actual game —it’s specifically the old man in the Celadon restaurant.

TL;DR: Go to Celadon City → head south past the Game Corner → enter the small restaurant on the right → talk to the angry bald man in the back-left → he hands you the Coin Case.
