Lawson Shearer. On May 18, 2009, a specimen note was presented to the former Prime Minister's widow, Dr. Denise Eldemire-Shearer. Finance Minister Audley Shaw criticized the decision to introduce the banknote, saying that the introduction of such a banknote is a sign that the Jamaican dollar is losing value. On 15 November 2010, the Bank of Jamaica issued a commemorative note to celebrate its founding. The note is similar to its regular issue in design and security features, but the bank's logo printed in blue, with the words "50th anniversary" and "1960–2010" printed above and below the logo. The back of the commemorative note features the Bank of Jamaica headquarters building in Nethersole Place set against a background of morning glory blossoms. Both the commemorative and the regular issue note circulate in parallel. In 2012, the Bank of Jamaica introduced a new family of banknotes commemorating the country's Golden Jubilee. The commemorative banknotes are similar to its regular issue banknotes, but on the obverse it features the "Jamaica 50" logo superimposed on the watermark on the front of each note.

It formerly appeared on the note, which was in circulation from 1969 to 1994. Currently, the Jamaican banknotes are printed on a cotton material which has a relatively short life in the country's tropical climate and other circulation conditions, but the new notes will come on enhanced substrates. The note is printed on a material called "hybrid", a combination of a protected polyester film layered on a cotton fiber core. The , , and notes are printed on a varnished cotton substrate, that is, the traditional cotton treated with a varnish after the notes have been printed. Varnishing creates a moisture-proof layer to protect the banknotes against surface soiling and reduces the extent to which they will absorb moisture, contaminant particles and microorganisms. The note remains on a regular cotton substrate as the main security thread, "Optiks", is compatible only with the cotton based material. The commemorative notes are released into circulation on 23 July 2012 and the new notes will circulate alongside the regular issue banknotes. On 24 March 2014, the Bank of Jamaica issued a note printed on the "Hybrid" substrate. In 2015, the Bank of Jamaica
