Azores 1200 Réis (1887) Luis I, Crowned G.P. countermark on 1815 R Brazil 960 Réis of Jose I
NGC XF45 with standard almost uncirculated countermark.
This host coin appears to be struck over another 1813 dated coin. which can be seen around 10:00 - 11:00 on the obverse.
NGC did not notice this, and there for document this in any way. But it is clear that there is an under-type of some kind.
It seems that all of these (1887) countermarked coins are scare to extremely rare.
Decree of March 31, 1887
The second decree ordained that all foreign silver and copper coinage circulating in the Azores was to be countermarked with a crowned G.P. (Govern now Portuguese) within a circle. These were eventually to be replaced or exchanged by the current Portuguese coinage upon their entry into the public treasury. This countermark for general use is found on a variety of Portuguese, Brazilian, and foreign issues.
This countermark has been heavily counterfeited and should be approached with caution.
