There are two main currencies in Animal Crossing: Pocket Camp, each with its own purpose:

Bells
Bells are the standard in-game currency. You'll earn Bells by fulfilling animal requests, selling items, and completing goals. Bells are used for:
- Purchasing furniture and clothing from the Market Place.
- Paying for crafting costs (though materials are often the primary cost).
- Upgrading your camper.
- Buying items from other players' Market Boxes.
Always try to keep a healthy supply of Bells by regularly completing requests and selling excess items.
Leaf Tickets
Leaf Tickets are the premium currency. While they can be purchased with real money, you can also earn them through:
- Completing Timed Goals and Stretch Goals.
- Leveling up your character.
- Logging in daily (sometimes as a bonus).
- Participating in special events.
Leaf Tickets are best saved for:
- Speeding up crafting times.
- Purchasing special fortune cookies for rare items.
- Buying exclusive event items or special furniture.
- Expanding your inventory space.
Use Leaf Tickets wisely, as they are more scarce than Bells.
