The Brazil coin was struck over a Spanish coin like this one:

The abdication of the King of Spain, Charles IV, and the imprisonment of Ferdinand VII by Napoleon left mint officials in Spanish America scrambling for suitable portraits of the new king for coins.

Mint officials in Mexico City, Lima, and Santiago created imaginary busts of Ferdinand for their issues of 1808-11 from old portraits of Ferdinand and their imaginations. These busts differed from mint to mint with the Lima issues departing the furthest from what the King actually looked like.

Enough of the Spanish coin remains on the Brazil to identify the under coin as having the Lima imaginary bust only which means that the under coin was minted in Lima from 1808 to 1811. Unfortunately the under coin date does not appear.

The letters on my Spanish coin do not exactly match my Brazilian coin letters as the coin dies were prepared by individual artists then.
