1991 - 10 Nuevos Soles banknote

The security thread is a plastic strip that is inserted into the paper. Hold the banknote up to a light source and the text PERU 10 will appear crisp without any irregularities.

On the front there is a circle, actually an Inca design depicting the head of a Puma. On the back there is a ring and the center part is white. Holding the banknote up to a light source both images should line-up perfectly (Banknotes issued before 2011).

By placing the banknote horizontally in front of the eye, start tilting it up/down. The value of 10 should appear (Banknotes issued before 2011).

By using a magnifying glass the micro lettering PERU should appear repeatedly in the number 10 (bill value) (Banknotes issued before 2011).

Around the personality on the banknote is a shadow created by using micro lettering of the word PERU (Banknotes issued before 2011).

Under the writing "Banco Central de Reserva del Perú" (top left corner) is a line created with micro lettering (repeatedly the text: BANCO CENTRAL DE RESERVA DEL PERU) - for Banknotes issued before 2011.

Below the National Emblem (right side) is the value of the banknote printed with optical variable ink. By placing the banknote horizontally in front of the eye, start tilting it up/down. The 10 changes from fuchsia to gold-green (Banknotes issued before 2011).
