Proof Gold Eagle Sets

With gold at $400 an ounce, why aren't these sets going up in price. I guess if the mint charges more, the older sets will go up in price. No one seems very interested.

The Mint already has a big profit built into their bullion.

I’m sure that has contributed to keeping the prices down.
1)The quantity buyers are telemarketers who put the sets into customers IRA accounts. They have a set level the like to pay that stays the same whether gold goes up or down.
2)Demand is pretty steady. When gold is low there aren't as many sets available and the premium goes up. I remember a few years ago the premium was $250 an oz over gold. When gold goes up all the sudden people start selling their proof gold eagles and there are more on the market. That means the premium goes down.
