The Sporewiki article about rares says this about rares collections: "Alternatively these collections can be left on a planet inhabited by a pre-space sentient race to grant a heavy bonus to your relationship with them when they advance to the Space stage and also a great reduction in cost of goods in that planet's trade window."

However, there is no way to drop the collection as a whole since it only appears as a collection in trading window. I have tried dropping all 10 items that make up the collection on a planet with creature in tribal or civilization stage (tried both of them), then placing a monolith on the planet and waiting until they evolve into Space stage. This didn't give me any bonus in relationship with them or price reduction in their shops. Is there any way to make this work?
