Antique Victorian signed 1880s rose gold filled etched fern leaves cufflinks

Great antique condition, fronts are in remarkably good shape at 140+ years old and nearly all rubbing is located on underside. One cufflink connective bar is slightly misshapen but both hinged buttons function perfectly. These are both faintly stamped with a patent date (year is either 1880 or 1889, difficult to make out). Fronts measure 0.69 with hand-etched ferns. These were and still are unisex.          Tags: collectibles accessories leaf floral 1800s rare estate jewelry
