Brazil 1939 2000 reis - unusual flan and edge? [Risolto]

Out of average dozen Brazilian coins I got on eBay I pulled this nice looking 1939 2000 reis specimen and started posting it, but the flan and the edge immediately drew my attention - it is not a round flan, but rather appear to be a 24-sided flan with some unusual partial and very week reeding. By the way Nimista catalog lists the edge as smooth while Krause states a reeded edge. Any additional information will be much appreciated.

Um, this is not a 200 réis coin, it's a 2000 réis coin.

And the 2000 réis coin is indeed a 24-sided disk (https://en.numista.com/catalogue/pieces6776.html).

Many thanks! I missed the part of Numista definition of the coin, it is clear now.
