What does the design cost you on palladium collector coins?

A Lunar, Koala or Panda holds the same palladium as a plain bar. The difference is in the design, which changes every year, and in the mintage. Below are 0 series with a comparison of their own, each with its cheapest route to the metal, sorted by what you pay over the metal value. Half of all 2 series editions sit above 42%.

For comparison: the cheapest plain route to an ounce of palladium costs 27.61% over spot (Palladiumbaar 1 kg). The median here pays 42%. That difference is what the design costs.

These coins are not on the ounce board, and that is deliberate. Someone buying metal by weight is helped by the cheapest route; a series with an annual design would sink to the bottom of a list it does not belong on. Whether the premium is worth it depends on something we cannot measure: whether the mintage and the design later find a buyer who pays more for them.
