The 20th Anniversary Gold Eagle Set was issued by the US Mint to celebrate the 20th Anniversary of the popular gold bullion and collector coin series. Each set contained three coins: the 2006-W Proof Gold Eagle, the 2006-W Uncirculated Gold Eagle, and the 2006-W Reverse Proof Gold Eagle.
The collectible proof and uncirculated coins contained in the set were available in other US Mint product offerings, but the 2006-W Reverse Proof Gold Eagle was unique to the set. It was also the first time that the US Mint had used this type of finish. The raised design elements of the coin are mirrored and the background fields are frosted. This is the reverse of the typical cameo proof finish.
The 20th Anniversary Gold Eagle Sets went on sale at the United States Mint on August 30, 2006. They were priced at $2,610 with an ordering limit of ten sets per household and a maximum production of 10,000. After approximately one month, the sets sold out and strong premiums developed on the secondary market for this unique product.
Separately, the US Mint offered the 20th Anniversary Gold and Silver Eagle Set. This set contained the one ounce 2006-W Uncirculated Silver Eagle and one ounce 2006-W Uncirculated Gold Eagle. This set was priced at $850, with a maximum production of 20,000, and limited to ten sets per household. The entire maximum production was sold after a number of months.
The major third party coin grading firms PCGS and NGC attribute coins from these sets as “20th Anniversary” as long as the customer submitted the coins in the unopened shipping box.
