large and bold Mermod Jaccard wreath pin circa 1870,

probably a crest and we suspect Missouri-related given the maker. Great quality and weight; the condition is unassailable when viewed from the front but from the reverse (see second photo) it is obvious that there have been some different findings attached in years past... 2 5/8 by 2 1/8 inches, no monogram, marked "Mermod & Jaccard / Solid Silver".
