In Baldi's Basics Classic, the Quarter is the first item the Player can obtain after successfully completing Baldi's first three math problems from the beginning of the game, and obtaining the first notebook. The Quarter can also be found in hallways randomly and one of the Faculty Rooms with the Alarm Clock item.
Ironically, a Quarter costs 25 You Thought Points, and a Quarter represents 25 cents in real life.
Baldi's Basics Classic
Before V1.3, there were only two Quarters the Player could find.
The feature of Quarters spawning randomly in halls was implemented in the V1.3 update.
The Quarter and It's a Bully have the same spawn points. This can be seen if the Player gives him an item and when he vanishes, there's a small chance a quarter could be in the exact same position.
