To get the best rewards, including upgrade materials and in-game currency, you’ll need to collect all the collectibles. Here are all the HIA Commemorative Coin locations in Zenless Ground Zero.
This list is a WIP and will be updated as soon as possible!
Where to find all HIA commemorative coins on ZZZ
To find all the HIA commemorative coins in ZZZ, you have to talk to passersby. You have to look for them at any time of the day (and night) to get them all.
You can trade these coins for valuable items and Dennies from the Sage at the Barrel, a trash can at the end of the street near Store 141. You’ll also get a medal when you collect half of the coins in a single area – just talk to Officer Mewmew, located right outside Howl’s Newsstand.
The quickest way to check if you can get coins at that time is to click on the time of day at the top. If the text tells you that Sage wants more coins, that means you can find someone who will give you a HIA coin.
Don’t worry, you don’t have to go around talking to everyone. People who have coins will have a grey speech bubble above their heads. Sometimes all you have to do is talk to them, and sometimes you’ll have to do something quick or pay them. It usually only takes a minute or two, which isn’t a waste of time considering the huge rewards.
When it comes to coin items, they will have a shiny effect around them, so you should know that you need to check the item.
All Sixth Street HIA Commemorative Coin Locations at Zenless Ground Zero
Tomorrow
#1 Ellis
To start your collection, you’ll first need to speak to Ellis at the Noodle Shop, who will ask you to investigate the trash can at the end of the street. Ellis will also give you your first HIA Commemorative Coin.
#2 Mrs. Yani
You can find Ms. Yani by the street sign across the street from the remodeling shop. You’ll need to go check if shop 141 accepts the HIA coin. Once you tell Ms. Yani that it doesn’t, she’ll give it to you.
#3 Sjal
You can find Sjal handing out flyers in front of the noodle shop in the morning. She will simply give you the coin.
#4 Plants
Late
#5 Travis
Travis will be right outside the video store, so it won’t be hard to miss him. Talk to him to get the HIA Commemorative Coin.
#6 Clara
You’ll find Clara standing in front of the street sign in front of the remodeling shop. She’ll ask you to take a photo of her. Once you do, she’ll give you the HIA Coin.
#7 Lupita
You can find and talk to Lupita across the street from Store 141 during the afternoon.
#8 Panda
The toy panda will be sitting in the cafe drinking a beverage. Besides being extremely cute, if you look at it, you will receive a HIA coin.
Record box no. 9
You can loot the left register box in front of the Bardic Needle shop in the afternoon for a HIA Coin.
Evening
#10 Jonah
You’ll find Jonnah in front of the Godfinger Gallery. He’ll trade it to you for Godfinger Tokens, which you’ll need to give him when you see him in the gallery.
#11 Roy
Roy will be standing in front of shop 141, so you can ask him for the coin. He’ll ask for 300 Dennies for it, so make sure you have some (though that’s not terribly difficult).
Locker #12
After you’ve collected some coins, check the locker next to the workbench in the shop at night.
#13 Garbage container
You’ll need to search the dumpsters at night for a HIA Commemorative Coin. This is the dumpster right behind Officer Mewmew.
