NETHERLANDS EAST INDIES. Sumatra (under Kingdom of the Netherlands). 1/4 Stiver (Duit), 1821-S. Surabaya Mint. NGC VF Details--Environmental Damage.
cf. KM-287 (unlisted date); Sch-Unlisted. Fairly RARE and interesting, this issue predates the known striking of the denomination by a whole year, as 1/4 Stivers aren't recorded until 1822. The corresponding larger denomination (1/2 Stiver) had production beginning in 1820, so this example may well likely be part of a very brief early emission of the 1/4 Stivers in 1821.
Estimate: $600 - $800
