Prior to the publication of the 3rd edition store card book, this pre-Civil War merchant token was listed as a Civil War store card. It was actually struck around 1858. Unlike most merchant tokens produced in the 1850's, the style of this token is consistent with Civil War tokens issued a few years later. It expresses a sentiment that "pure copper is preferable to paper" and this was also true during the Civil War.
This is an attractive uncirculated specimen struck on a copper planchet that is a little thicker than the typical Civil War token.
