in 2010, the Central Bank of Brazil announced a new series of Brazilian real banknotes. The new banknotes have begun to enter circulation in 2010, coexisting with the older ones.
The newly designed banknotes have more security enhancements, such as a new holographic strip to prevent counterfeiting. The notes also have different sizes according to their values to help vision-impaired people. Although there are some changes in the design of the new banknotes, the figures and animals on the notes remain the same and also the color of the notes remains unchanged.
The 50 and 100 real notes were issued first because they are the most forged banknotes, and the new 20 and 10 real bills released in 2011. The whole process will be finished by 2012, with the launch of the new 5 and 2 real notes. Older banknotes will remain in circulation during the whole process.
