KM-479-1, S-3422, 41.6 grams, 37mm. Conjoined laureate busts right, GVLIELMVS.ET.MARIA.DEI.GRATIA, toothed border on both sides, reverse: crowned quartered shield with escutcheon of the Lion of Nassau with 11 lozenges, seven strings to Irish harp, date 1692 at top, .MAG.BR.FR.ET.HIB.REX.ET.REGINA. Mary Stuart was the daughter of James II and married William III as part of Charles II's foreign policy. William and Mary reigned jointly from 1688 until her death from smallpox at the young age of 32 in 1694. The Five Guinea piece was the largest of their gold coins and featured the conjoined busts of the two monarchs, as this was the only time in British history that joint monarchs' portraits appeared on currency. All William and Mary coins are rare in high grade and this near-Mint piece is no exception, with a pleasant red tone. A simply lovely example retaining its original mint brilliance.
