Zenless Zone Zero: All HIA Commemorative Coins on the Brant Street Construction Site

Sage in a Barrel is looking for someone to help it find all HIA Commemorative Coins. These coins can be found in Sixth Street and Brant Street Construction Site, and after collecting them, you can give them to the Sage in a Barrel for various rewards.

There are a total of 28 HIA Commemorative Coins, 18 of them are in the Sixth Street and the remaining 10 are in the Brant Street Construction.
This guide is for Brant Street Construction Site only, if you want to see the Coins' location on Sixth Street, look here: All HIA Commemorative Coins on Sixth Street


Where to Start the HIA Commemorative Coin Commission

First of all, talk to Elis at the Noodle Shop in the morning/afternoon and he will introduce you to the Sage in a Barrel and the coin-finding mechanic.

After that, you can see the navigation leads you to a trash can. This is the Sage in the Barrel and you need to find Commemorative Coins for it. Go back to Elis and you will complete the commission for now. The next thing you need to do is to find all the coins.

Tips on Finding the Commemorative Coins

If an NPC can be interacted with and have a grey speech bubble above their head, they will give you a coin.

If an object has a coin, however, it will have sparkles around it.

You can also check the New Eridu Time (on the top left corner) as it will show a list of activities that can be done near your location.

If there's an activity about 'Sage in a Barrel wants more Commemorative Coins,' that means there should be a coin somewhere in the area.

If you still don't know what to do, you can talk to Sage in a Barrel and ask for a hint by clicking the 'Gather Info.'

In addition, you can also see how many HIA Commemorative Coins you've got left to find by seeing how many items it has left to give you. That number is the number of HIA Commemorative Coins you've got left to find.


All 10 HIA Commemorative Coins on Brant Street Construction

Tips: In each timeframe, after talking to the NPC who gives out Commemorative Coins, teleport to another map (outside of Brant Street Construction) and teleport back into the construction site to refresh the NPCs' location. This way, you can collect all the coins in the same timeframe.


All the coins below are in the morning.

HIA Commemorative Coin #19

In the morning, teleport to the Maintenance Area and you will see Kaede on the left side near Grace. Talk to her first.

Then, look at the direction she's looking at to see another construction worker. Talk to Cole and then to Kaede again to get your coin.

HIA Commemorative Coin #20

In the morning, teleport to the Storage Area and go to the left side until you see Becky. Just talk to her and you will get the Commemorative Coin.

HIA Commemorative Coin #21

In the morning, teleport to the Storage Area and go to the left side until you see Luka (same place as Becky before). Talk to him and choose whether you want to give him 500 or 50 Dennies. I choose the latter.

HIA Commemorative Coin #22

In the morning, teleport to the Maintenance Area and look a bit to the right side and you will see Ronnie beside the elevator. Talk to her and take a picture of Kousaka just ahead of her.
If she didn't appear at all even after refreshing the map, try completing the mission "Hands and the Art of Cement Mixer Maintenance" since it's also related to Kousaka.


All the coins below are in the afternoon.
