This is an extremely rare cut half segment of a Charles III Spanish Silver Dollar, counter stamped SV (St. Vincent) three times within a plain rectangular indent with bevelled corners.
On 8 December 1797, an Act was introduced to prohibit and control the importation of counterfeit coins into the colony of St. Vincent.
The Act also aimed to regulate and legitimise the currency by overstamping cut dollars with the stamp 'SV'.
The Act saw the formation of a Committee to oversee the stamping of the half dollars.
The Committee was required to affix the stamp SV within 30 days of the passing of the Act.
The Committee was also charged with the responsibility of punishing counterfeiters.
