I would like to know how close I am to Gholdengo. Also, if you’ve collected 999 coins, does that mean you can always evolve Gimmighoul or is it reset each time?
Gimmighoul coins are stored in the TM Materials section of the bag, and they are used up when you level up a Gimmighoul while you have 999.
