A sellout was declared for the American Eagle 20th Anniversary Silver Coin Set featuring three of the one-ounce silver coins. Mint operators said no more were available as of Nov. 13.
Priced at $100 each, the sets contain a proof, reverse proof and a ?W? mintmarked uncirculated coin.
Demand was spurred on by secondary marketers buying them up from original buyers in hopes of getting unopened sets slabbed in grades at the top end of the proof and uncirculated grading scale.
Unopened sets were submitted to third-party grading services for them to certify, giving the exercise a lottery feel.
