antique 19th century coin silver spoons, 6 sterling teaspoons

Six matched tea spoons, 1800s vintage coin silver (90% pure silver alloy, used for flatware and some hollowware, before the use of sterling silver became widespread).

These are 5 3/4" long, all in very nice condition, with a small PTL hallmark. The underside of the handles are engraved with the owners initials (JJK and ARK, we think?)
