2008-W 1 oz. Platinum Unc.

This 1 oz. coin was purchased due to it's extremely low production. It's the lowest production on any of the 1 oz. coins, Proof or Unc. What I can't understand is when I go to different auctions to see what the coins are going for the Proof is selling for more even though it has the higher mintage of the two. This coin comes from a mintage of 4063 or so and the Proof comes from a mintage of 5100 or so. As you can see both mintages are quite small. Thinking I was smart I bought 2 of the Unc's thinking they would climb higher in value compared to the Proofs but this is proofing to be incorrect. Maybe time will tell and the tables will turn. We'll have to wait and see I guess.
