This coin is a 1 Stuiver which is on the reverse side with a star in thelower field. The obverse has Curacao in the upper field, the date, 1822 inthe middle field and a star in the lower field below a line. The coin wasminted in the Netherlands (as Denmark minted coinage for use in the DanishWest Indies) in 1822 and then the dies were used again when it was alsostruck in 1840-1841. So even though it carries the date 1822, it may havebeen minted in 1840-41. It circulated at that later date as a 2 Centpiece. The star was the mint privy mark for the either the Enkhuizen mintor the Hoorn mint in West Friesland, The Netherlands.
This was shortly after the second British occupation of Curacao during theNapoleonic Wars (1800-1803 and 1807-1816.)

BTW it is probably worth less than $100 on the World Coin market. Thecondition would be "Fine." This is the lowest condition assigned. Of course it is invaluable as a part of the excavation in Cinnamon Bay."
