1/4 Crown - Elizabeth II 2nd portrait

The Turks and Caicos Islands adopted the quarter crown as their principal circulation unit in the 1970s, a deliberate break from the US dollar system that had dominated informal commerce on the islands for decades. The crown-based denomination was largely a political statement by the colonial administration, though US dollars remained the currency of daily transactions regardless of what was struck in copper-nickel.

KM#51 corresponds to the Maklouf portrait, introduced across British territories in 1985 — but this piece dates to 1981, when the Machin effigy was still current. Worth confirming the portrait attribution against physical inspection before cataloging further.
