What to do with HIA Commemorative Coins on Sixth Street

Turn in your HIA Commemorative Coins to the Sage in a Barrel in Sixth Street to get Senior Investigator Logs, W-Engine Energy, and Denny rewards in Zenless Zone Zero. While there aren’t specific reward milestones like with Officer Mewmew’s medals, the general rule is the more HIA Commemorative Coins you turn in, the more rewards you get.

Where is the Trash Talking in ZZZ

To unlock the Sage in Barrel NPC, you must complete the Trash Talking side quest. To do so, speak with Elis, the blond man in a suit in the Ramen shop to receive the quest. To find the talking trash can, wait until the evening and head to the street corner in front of Coff Coffee and next to the magazine stand.

The Sage inside the trash can asks you to find HIA Commemorative Coins for him and your quest for hunting them all begins. Report back to Elis to complete the quest and get the first HIA Commemorative coin.
