HIA Commemorative Coins are a collectible that players can find in Zenless Zone Zero (ZZZ). Each major map in the ZZZ has its collection of HIA Commemorative Coins, so in this guide, we will detail where to find the ones located on Lumina Square.

What Are HIA Commemorative Coins?

HIA Commemorative Coins, as mentioned above, are collectible items that players can find scattered in each major map. After collecting these coins, players can turn them over to the Sage in a Barrel, who in turn will reward the player with various rewards, such as EXP Materials, Polychromes, and more.

Talking to the Sage in a Barrel will also tell the player how many coins they still have to find.

It's important to note that areas share coin counts with other areas. In this case, Lumina Square shares coin counts with Ballet Twins Road, so keep that in mind while playing ZZZ.

Additionally, the coins found in Lumina Square and Ballet Twins Road are called HIA Commemorative Coins: Radiant. They are not interchangeable with the HIA Commemorative Coins found in Sixth Street and Brant Street.

The coins players can find will depend on the time of day. Morning, Afternoon, Evening, and Midnight cycles each have different coins for the player to find. Additionally, only one coin spawns per period. Once players find a coin, they will need to advance the time to find another one.
