This coin vs Brazil KM# 301 [gelöst]

I've recently purchased one of these coins from eBay. I was wondering if it should be listed under this entry or N#162835 for consistency's sake. Based on the text on this page, I'm leaning towards it counting for Brazil, not Angola. Any advice?

I've recently purchased one of these coins from eBay. I was wondering if it should be listed under this entry or N#162835 for consistency's sake. Based on the text on this page, I'm leaning towards it counting for Brazil, not Angola. Any advice?

In the link of the 80 Réis from Angola, theres a comment that says:

This coin was issued by law "Rio de Janeiro, Alvará 18APR1809" during the time Portugal was occupied by Napoleon Bonaparte.
The law has only been executed in Brazil. Therefore, this coin belongs only to Brazil.
Traditionally is also considered from Angola. However, such a coin has never been found there.

So, if it has the Shield Countermark. its is a coin from Brazil. If it dont have the Shield Countermark, can be both Brazil or Angola.
