Turks and Caicos 1980 5 crowns piedfort

Had this coin for a while, and can't find it in the catalogue. I did look about adding it, but the page said “article is under preparation”

Diameter is 34.7mm, thickness 4.9mm weight is 30.3 grams, these are approximate as the coin is in a thin plastic capsule. The inscription on the smooth edge reads “ REDEEMABLE AT TURKS AND CAICOS FOR U.S.  CURRENCY”

Seems to be a larger version of this one:  N#78715

Maybe two coins in one?

Edit: Yes, piedfort.  In SCWS as P1

Thanks for the information, seems quite a scarce coin.
