There are 5 Medallions at the Farm. Shooting them all will get you 3 Spinels.
1. Backside of the typewriter building.
2. Inside the middle barn. I got it through the southwest window.
3. Inside the rafters of the west building.
4. East two story building, hanging in an upper window.
5. Behind the Wayshrine in the gated area. Go through the windmill to get to it, and it’s hanging from the windmill balcony when you jump down.
