Watch List notes:

Essequibo & Demerary Half Guilder 1816 KM#12 EF/AU a rare one-year type, our archive database shows that we have only previously offered one example, that coin being way back in 2004. In the light of this, probably scarcer than catalogue values may suggest. Note: The area was not ceded to the British by the Dutch until 1814, and the Three colonies of Essequibo, Demerary and Berbice were eventually united in the British Crown Colony of British Guiana in 1831

Estimate: 200-250 GBP
