Each coin identifies the place of coinage and also the person responsible for the law of the coin (purity and weight) called the assayer. Usually the initials of the names were used and could be one or two assayers by minting. In the case of Philippines well into the nineteenth century also included the person responsible for balance. This is an example of how to identify these signs in coins.

Santiago (Chile) 1809 8 Reales rancisco Rodriguez Brochero & Juan Maria de Bobadilla
As we have already had opportunity to comment, the death of a monarch had to wait a while for the arrival of its corresponding model of bust from the Peninsula. The case of Fernando VII is particular, its arrival to the throne in March of 1808 is accompanied with the Napoleonic invasion that forced the mints to make their own busts that we know as imaginary. In this case the dress is not Roman style but of time.
Santiago (Chile) 1790 8 Reales omingo de Eyzaguirre y Agustin de Infante y Prado
Although Charles III had died on December 14, 1788, his bust continued to appear on the coins until 1791 at which time the official bust of the new monarch, Charles IV, was prepared. There are transitional pieces like the one in which only the ordinal of the king has been changed. The essay corresponded to Eyzaguirre and Infante responsible for the law in the first coinage of the new monarch.

First year of the imaginary bust of the mint of Lima. The portrait did not last more than four years and was coined in different sizes being the corresponding to 1808 the largest by far. The reason for the need to make imaginary portraits based on paintings from the Kingdom of Spain is none other than the Napoleonic invasion. The portraits of the monarchs arrived late to the colonies, which is why the portraits of Fernando VII were called until 1812 "Imaginarios". The portrait on which this bust was based was made in America by a local artist and that is why it is called Fernando VII the Inca or also known as bust of Indian.
