Owlboy Owl Temple Coins: How to Collect Them
Where Owlboy's Owl Temple coins and treasure hunting fit: the Owl Temple, the Buccanary Shop, Coupon Rings and the Treasure Seeker achievements.

How do I find all the coins in the Owl Temple in Owlboy?

There is no officially documented coin checklist for the Owl Temple, and the patch notes do not list one. What is documented is how the game's collectible currency works: Coupon Rings award coins when you fly through them. Inside the Owl Temple itself, the documented material covers the temple's role in the story rather than a coin-by-coin layout, so treat any "all coins in the Owl Temple" route as player-made rather than official.
What is the Owl Temple?
The Owl Temple is one of the oldest owl ruins known, according to the community wiki's Bonfire page. The same page notes that the control room sits deep inside the temple. It also appears in the backstory of Otus's allies: according to the wiki's Alphonse page, Alphonse and Dirk crashed their ship in the Owl Temple. According to the wiki's Bonfire page, the cloaked weirdo recited that by the end of the first aeon the owls had mastered water, fire and wind.
How do you collect coins inside it?
By flying through Coupon Rings as you explore. According to the community wiki's Buccanary Coins page, collecting a Coupon Ring earns you 3 coins per ring. The official Anniversary Update notes add quality-of-life changes that help while sweeping a level for pickups: pickups are now thrown in the direction Otus is flying when pressing the Throw button, and a Super Dash can be triggered by holding the roll button for extra speed. The notes do not describe any Owl Temple coin location.
How do Coupon Rings work?
Most are collected by simply flying through them. Some, however, need to be flown through as a set, in any order, to collect all of them, according to the community wiki's Buccanary Coins page. That set behaviour matters for a full clear, because a single pass through one ring in a group is not the same as completing the group.
What can you buy at the Buccanary Shop?
The shop sells range upgrades for Otus's gunners. According to the community wiki's archived Combat page, a scope from the Buccanary Shop extends Geddy's range, and an extension from the same shop extends Alphonse's range.
Which achievements track coin hunting?
Treasure Seeker and Treasure Seeker Grand Master are the documented coin achievements. According to the community wiki's Buccanary Coins page, collecting a lot of them earns the Treasure Seeker achievement, and collecting all of them earns Treasure Seeker Grand Master. On Steam the game lists 12 achievements in total, and Treasure Seeker is one of the highlighted ones on the store page.
