1999 Dollar Pattern - J-2188
Strike TypeCoin Details
Description
The 1999 Dollar Pattern - J-2188 is a Martha Washington dollar-size trial in a non-manganese alloy with a dotted letter N on each side of the obverse field. 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). A Treasury letter with the first one offered explains that the samples were to field-test two alloy systems for the new dollar against slugs, and the Heritage piece tested at 77% copper, 20% zinc and 3% nickel with a plain edge. About 50 were known with the dotted N's as of 2017 (USPatterns.com). NGC lists it as 1759(1999) J-2188 $1.
