The world of Pokémon GO continues to evolve, and with the game’s 9th Anniversary celebration, Niantic introduced a unique and exciting item—the Coin Bag. Designed to bring a fresh challenge to players, the Coin Bag unlocks special encounters and is essential for catching the elusive Pokémon Gimmighoul and ultimately evolving it into Gholdengo. However, obtaining this item requires more than just spinning PokéStops or completing Field Research—it demands a cross-platform connection with your Nintendo Switch.

In this guide, we’ll walk you through every step to get your hands on the Coin Bag in Pokémon GO, how it works, and why it’s worth the effort.

What Is the Coin Bag in Pokémon GO?

The Coin Bag functions similarly to the Mystery Box used for Meltan. Once activated, it allows Gimmighoul to spawn around your avatar for a limited time, giving you the opportunity to catch multiple Gimmighouls during the window.

This feature is not only tied to Pokémon GO’s expanding Pokédex but also to the broader Nintendo Switch ecosystem, encouraging players to engage with Pokémon Scarlet or Violet. As of now, the Coin Bag is the only reliable way to encounter Roaming Form Gimmighoul in Pokémon GO.

Step-by-Step: How to Get the Coin Bag in Pokémon GO

1. Set Up the Nintendo Switch Connection

To begin, open Pokémon GO and head into the Settings menu. From there:

• Scroll to Connected Devices and Services

• Tap Nintendo Switch

• Choose Connect to Nintendo Switch

This step prepares your GO account to pair with the Switch system.

2. Switch to Scarlet or Violet

Boot up Pokémon Scarlet or Violet on your Nintendo Switch. Navigate to the PokePortal, and select Mystery Gift. Within this menu, select:

• Connect with Pokémon GO

• Pair with a Pokémon GO account

Both devices will now enter a pairing mode. Once they detect each other, confirm the connection on both sides.

3. Send a Postcard

Now that your accounts are linked:

• Open Pokémon GO

• Go to your Postcard Book (found in your inventory)

• Choose any postcard and tap Send to Nintendo Switch

Sending a postcard not only rewards you with the Coin Bag but also unlocks the opportunity to obtain Golden Lure Modules, which are vital for farming Gimmighoul Coins.

Using the Coin Bag and Catching Gimmighoul

Once you’ve received your Coin Bag, activate it from your inventory. For the next 30 minutes, Gimmighoul will appear around your character—just like other incense or lure effects.

Tips:

• Use this time efficiently—walk around to maximize spawns.

• Consider using Pinap Berries to double the Gimmighoul Candy.

• You can use the Coin Bag once per day, but only after sending another postcard.

Evolving Gimmighoul Into Gholdengo

Evolving Gimmighoul requires 999 Gimmighoul Coins, a hefty requirement. You can obtain more coins by:

• Catching Gimmighoul from Coin Bag encounters

• Using Golden Lure Modules on PokéStops

• Spinning those Lure-enhanced PokéStops to collect coins

Golden Lures can only be acquired by sending additional postcards, one per day. So, evolving Gholdengo is a long-term goal that rewards consistent play and planning.

Final Tips & Summary

• Coin Bag = Only available via Pokémon Scarlet/Violet + postcard

• Send postcards daily to maximize Coin Bag usage and farm coins

• Golden Lures enhance coin farming but require multiple postcards

• 999 Coins = Gholdengo Evolution – stay consistent!

The Coin Bag is a unique mechanic that adds a layer of strategic planning to Pokémon GO. By connecting your accounts and utilizing postcards smartly, you can unlock one of the game’s rarest evolutions and enhance your collection with exclusive forms.
