Guinean franc

This series was printed without imprint by Thomas De La Rue, and includes more colors, enhanced embossing, and improved security features.

[2] In 2010, a commemorative series of 1000, 5000, and 10,000 francs banknotes celebrating the fiftieth anniversary of both the Guinean franc and the Banque Centrale de la République de Guinée (BCRG)[3] was issued featuring a diamond-shaped logo of the event on the front side of each denomination inside of the watermark window to the right.

The banknote's main color was changed from green to red, and instead of a diamond-shaped patch placed on the letters "RG" (for Republique de Guinée), it is now replaced by a holographic patch and the holographic security strip now showing on the reverse side.

[5] On January 21, 2018, the Central Bank of the Republic of Guinea issued a revised banknote of 20,000 francs, with a reduced size and advanced security features.

Currently, the smallest denomination in circulation is the 500 francs note due to diminished purchasing power.
