Coin Details
Description
The 1999 Proof Dollar Pattern - J-2185a is a Martha Washington manganese brass trial with six notches on the border. In 1999 the Mint used its second set of Martha Washington dies to test the golden manganese brass planchets later used for the Sacagawea dollar, and gave the dies to outside contractors such as IDX Inc., PMX Industries, Schuler AG and Olin Brass Corporation (USPatterns.com). USPatterns.com describes J-2185A as one of several apparent experiments for the blind, with six notches on the border, and counts at least three. PCGS lists it as (1999) $1 J-2185a (PCGS #813375).
