My only firsthand acquaintance with the Angolan 2-macutas is the small copper-nickel coin of 1927-28. It’s a coin that’s piqued my interest because of its double-denomination—and I like the allegorical portrait that adorns it—so I clicked on your thread thinking I would learn more about it.
What a surprise! Old copper, (very) big and heavy—it has to be fun to hold—and the added romance of an overstrike with a partially visible host-coin beneath. Scarce, too. Nice!
My 1801-1900 Krause
is old too, but it’s a little newer (2006). Your coin was still not illustrated, but had acquired a new catalog number (KM49). Of the three dates listed, 1815, 1816, and 1819, only the 1816 was accompanied by a mintage figure: 3,175.
But that was 11 years ago. I hope they’ve improved the Angola section since then.
Nice coin! Congratulations…
