Gold Coins

In order to unlock everything from the Gold Shop, you'll need a total of 56 coin clusters. There is an achievement for finding 65, but there at least two more to find. I've been able to find 67, but during the intervening months I've forgotten where one of them is. Feel free to reach out and let me know if you've spotted it or others. What makes this super fun is that each coin cluster you find is unique, so you can't just run through the game a couple times collecting the same coins and have the counter go up.

An important note is that this was tested primarily with the Quest 3 version, as reflected with the screenshots. Both the PCVR and PSVR2 versions moved the locations of some of these coin clusters around. I believe I've notated all the new locations, but feel free to email me if I missed any.

Spires of Agdor

None Entrance hall

There's a pile of crates and barrels blocking the doorway. Destroy them all to find these.

Burn the tapestry to the right of the red barrier to find these coins in a small recess.

Winding Stairs

Break the various pots on the first landing.

Inside Chest 1

Break the various pots on the second landing.

Destroy the barrel near the exit door.

The Cage

None The Alcoves

Break the pot near the Large Key
In PCVR, this is near the doorway and already shattered.

In the same alcove as the previous coins, open the hidden Chest 6

Pass the first blue barrier. In the alcove with the hidden rune plate to disable that barrier (across from Odin's perch), destroy the crate.

At the Save Point past the two blue barriers, burn the tapestry across from Odin's perch to reveal a hidden room. Break the barrels to find these.

Dark Halls

Break the barrel near the Message Sphere.

At the spot with a Lever to pick up and an illusory wall that hides a magic missile hallway, burn the tapestry to find this clutch of coins.

In the chasm room with the straight path of pillars to cross, head to the table with the Small Key and the Rune Tablet. Start climbing along the rope to return to the other side, but when you reach the wooden scaffolding in the corner climb down to reach a small ledge. Break open the crate here for these.

After passing the first magic missile hall and crossing the large chasm, break the barrel near the Save Point.
The PCVR and PSVR2 versions move this to the area with the exit door.

After the first magic missile wall, break the crate in front of the closed grate. This will be near the second Lever you can pick up.

As you enter the second magic missile hallway, there's a crate to the right that contains coins. Further down the hall, break the first barrel to find more coins.
The PCVR version moves these to the area with the exit door.
The PSVR2 leaves the barrel in place, but moves it to the other side of the hall. The crate is not there, but I'm not sure where it got moved to.

Inside the hidden Chest 11.

Inside Chest 12.

Break various barrels and pots near the exit door.
As previously mentioned, the PCVR version has two extra breakable objects here for coins.

The PSVR2 version moves this into the Dragon Cavern.

Smash the barrel near the Save Point.

Blue Room

At the bottom of the minecart tracks, approach the big door. Look to your left to spot a crate, which you can smash for some coins.

The Prison

None. Eastern Mineshaft

This is moved in the PSVR2 version. On the second landing, face the fountain. Turn left and move over the rubble into a small alcove to find this barrel.

On the first landing, smash the crate immediately to the left of the top of the stairs and the pot beside the Odin pedestal.

Inside the crate on the second landing.

Upon reaching the third landing, blow up the nearby barrel.
The PSVR2 version moves this into the Message Sphere room.

On the second floor, lure the Wraith out of the second cell. Enter the cell and shoot the crate in the corner for these coins.

Break the crate right beside the exit door.
The PSVR2 version moves this into Cell #10, so you can be this right after lowering the red barrier.

Stone Maze

Location: From the entrance, turn right and approach the relief on the wall. Break open the pot near its base for these.
In the PCVR and PSVR2 versions, this pot has been moved. From the entrance, turn left at the Save Point and smash the pot on the left wall.

In the room with the deadly pressure plate traps. Break open the green pot just beside the doorway, and the barrel near the back of the room.
