Zenless Zone Zero: Complete Guide to Brant Street Construction Site HIA Commemorative Coins (2026)

In the ever-evolving urban landscape of Zenless Zone Zero, the Brant Street Construction Site stands as a crucial hub for dedicated Proxies seeking valuable collectibles. As of 2026, this industrial zone remains a primary location for acquiring HIA Commemorative Coins, which are integral to the expansive Sixth Street collection. Securing these numismatic items rewards players with useful in-game resources and coveted Officer Mewmew Medals, though their precise whereabouts within the bustling site can often be ambiguous for newcomers. This guide provides a comprehensive, up-to-date walkthrough for locating every coin and maximizing your rewards from this significant area.

Understanding the Brant Street Collection

It is vital for players to recognize that the coins scattered throughout the Brant Street Construction Site are categorized under the Sixth Street HIA Commemorative Coin collection. This classification has a direct implication: the enigmatic Sage in the Barrel, the NPC who exchanges coins for rewards, is not physically present at the construction site. Consequently, after gathering these metallic tokens, Proxies must journey back to the familiar streets of Sixth Street to redeem their hard-earned prizes. The collection effort here contributes directly to two specific Officer Mewmew Medal achievements: one for obtaining half of the site's coins and another prestigious medal for securing the complete set.

Detailed Coin Locations & Acquisition Methods

The acquisition of each commemorative piece often involves interacting with specific non-playable characters (NPCs) at designated times of the in-game day—morning, afternoon, or evening. Some interactions are straightforward conversations, while others initiate brief multi-step quests. Here is the definitive list for 2026:

1. Becky (Morning): Locate Becky positioned near the Junction Box on the far right-hand side of the construction area during the morning hours. A simple dialogue will grant you the coin.

   

2. Gray (Afternoon): In the afternoon, seek out Gray, who is stationed near a truck parked in the top-right corner of the site.

   

3. Kaidou & Pepper (Afternoon): During the afternoon, find Kaidou loitering near the shipping containers in the top left-hand corner. After speaking with him, you must also converse with Pepper, a bear sitting idly nearby, and then return to Kaidou for the coin.

   

4. Luka (Morning): Return to the Junction Box on the far right side in the morning to meet Luka. He may request a monetary donation. Reports indicate a cost of 500 Dennies, though some players have successfully negotiated for 50 Dennies. This coin is typically obtainable after acquiring Becky's.

   

5. Kaede & Cole (Morning): Look for Kaede standing beside the left-hand elevator in the morning. Following your chat, approach Cole, who is leaning against the wall directly opposite her. A final discussion with Kaede will conclude the exchange.

   

6. Ironhead (Afternoon): On the right-hand side of the construction zone during the afternoon, you will encounter Ironhead. A direct conversation is all that's required.

   

7. Jen & Kaishu (Evening): As evening falls, locate Jen near some crates. She will direct you to Kaishu, who is positioned close to a blue shipping crate adjacent to your vehicle. Kaishu holds the final coin for this sequence.

   

8. Yang & the Builderboo (Evening): In the evening, head to the large pipes on the right-hand side to find Yang. After speaking with him, interact with a Sulking Builderboo concealed within the pipes. Once it emerges, engage with the creature again to receive your commemorative currency.

   

9. Li & the Cement Bag (Evening): Also during the evening, on the right side near some cement bags (often close to Yang's location), you'll find Li. Initiate a dialogue, then interact with the nearby cement bag before returning to Li for the final coin.

   

Redeeming Your Rewards: The Sage in the Barrel

As emphasized, the Brant Street coins belong to the Sixth Street anthology. Therefore, redemption occurs not at the dusty construction site but with the elusive Sage in the Barrel on Sixth Street. This mysterious figure is consistently found just past the local convenience store, at the turn where the road ascends toward the Metro Station.

A common issue reported by players is the Sage's initial reluctance to interact. If this occurs, a reliable troubleshooting method is to re-enter the Sixth Street area or advance the in-game time by a few hours. This typically resets the NPC's state and allows the exchange to proceed smoothly.

Pro Tips for Efficient Collection in 2026

• Time Management is Key: Plan your visits around the in-game clock. Grouping morning, afternoon, and evening trips can significantly streamline the collection process.

• Sequential Awareness: Note that some coins, like Luka's, may have prerequisites (e.g., obtaining Becky's coin first).

• Persistent Redemption: If the Sage is unresponsive, do not hesitate to use the re-entry or time-passing mechanics; it's a standard part of the interaction protocol.

By meticulously following this guide, Proxies can efficiently sweep the Brant Street Construction Site, adding a complete set of HIA Commemorative Coins to their Sixth Street collection and claiming their well-deserved Officer Mewmew Medals. Happy hunting in the vibrant, chaotic world of Zenless Zone Zero! 🪙🏗️
