Verified systemAncient Coins are a real collectible system in the release build. The opening tutorial shown in full-release footage says coins are hidden all along the coast, and that the rarest ones may be on the sea floor.

How the collection works

The first coin tutorial introduces a Collection Book. The footage shows the O key opening it, where each collected coin can be examined and its historical description read.

Where to search first

  • Around the coast and paths near the cafe.
  • On elevated walkways where sunlight can reveal a glint.
  • Around the town while travelling to shops and delivery destinations.
  • Underwater after diving becomes available; the tutorial explicitly hints that rare coins can be on the seabed.

Full map progress

The collection system and search approach are confirmed. A complete coordinate list from the release build is still being verified and will appear here as spots are confirmed.

Efficient collection routine

Combine coin hunting with required travel: record shop trips, supply runs, delivery routes and oyster diving. This reduces repeated walking while the database is still being verified.
