Pick 38 spans a long issuance window under multiple governor signatures, which is why dating individual examples requires checking the specific signatory pair rather than relying on the series date alone. Demas served as Central Bank Governor through the early 1980s oil boom years; Dookeran's signature appears on later printings issued during the sharp fiscal contraction that followed the collapse of petroleum revenues after 1982.
