2" which appears identical to item #349 but this version has a metal covered back with a center raised area holding a brass bar pin and with the embossed name of the button maker above "St. Louis Button Co." Trivial surface wear in reflected light with four pinpoint raised dots that catch light but are so small as to barely be noticeable to the touch. There is a pinpoint gray dot just above the letter "M" but very trivial and the button for practical purposes displays Mint. Hake #53 with 2004 Guide value of $600.00.
