2016 United States $1 Silver Eagle bullion coin. 1 troy ounce of 0.999 fine silver. This coin is graded by NGC as MS70, and is encapsulated in a Silver Eagle 30th anniversary holder, with the tag signed by Elizabeth Jones, the 11th Chief Engraver of the Mint (1981-91). The first woman to hold the post, she is greatly responsible for reinvigorating numismatism with her commemorative designs of the era, most notably the 1983-4 Olympic coins. The Silver Eagle also began during her time in the post.
