Occasionally when exploring Coral Island you'll come across items labelled as Artifacts. Artifacts are ancient, precious collectables from bygone eras. You can do three things with Artifacts:
  • Donate them to the Museum
  • Sell them
  • Give them to townsfolk as presents (though they're virtually never liked, regardless of the item)
Artifacts are one of several types of items that you can use to get the Museum up and running again, so it's generally wise to give the first iteration of an Artifact that you receive to the Museum, then sell any more you find. Donating Artifacts is one method for increasing your Town Rank, which unlocks additional items and services the higher your rank. Very important.


Though there are (or will be) a few ways to gather Artifacts, the primary method of acquiring these items is by opening Coffers. Take a Coffer you've found to the Blacksmith and they will charge you $20 to pop it open. You keep whatever's inside, whether it's a valuable Artifact or literal Trash. You can find Coffers in a number of different ways:
  • Dig in soil or sand with your Hoe
  • Break up rocks while Mining
  • Clear garbage piles while Diving
  • Purchase them from Ratih's Black Market, open at night by the Lighthouse on Monday, Tuesday, and Thursday - note that you can occasionally purchase Artifacts from Ratih as well, though she charges through the nose for each one

Below is a listing of all the Artifacts found in Coral Island as of now. Each listing includes the kind of Coffer you need to break open to receive the Artifact, as well as the sell price. There's a decent chance that this list will expand as more of the island is unveiled in future updates.
