On Friday, the US Mint officially sold out of the individual option for the one ounce 2011 Proof Gold Eagle. The coin does remain available for sale as part of the four coin set.
I believe this is the first 2011-dated US Mint numismatic product to achieve a sell out of the maximum product limit.
The 2011 Proof Gold Eagles originally went on sale April 20, 2011. The original price for the individual one ounce coin was $1,735, which was adjusted throughout the course of the offering based on the average market price of gold. During the course of the offering the price ranged from a low of $1,735 to a high of $2,135. At the time of the sell out, the price was $1,935.
The maximum product limit for the individual option was 30,000 coins. The limit for the four coin set is 40,000. Sales for the set have reached 11,765 based on the latest available data.
The individual one ounce 2011 Proof Gold Eagle had been just under the sell out level for some time. Near the end of August sales exceeded 29,000 units, and then reached 29,917 in the following week. For the next several weeks, sales reports indicated negative or minimal sales. Finally, the latest report covering the week ending October 10, showed a big jump which brought total sales back near the sell out mark.
The period of slow and negative sales figures coincided with the recent decline in the market price of gold.
In an interesting bit of news, the US Mint has recently extended their numismatic pricing grid to cover average gold market prices up to $2,999.99 per ounce. Previously the chart only went up to $2,049.99.
