A mule or a minting error?

I think this coin is not a mule, it is a very known minting error here in Brazil.

See the mule:

See the original 50 centavos :

See the 5 centavos coin origin of the mule reverse

What do you think?

So, as a coin error, would it need a page ?

I thought mules were minting errors?

Either way, I would think to keep mules as separate pages. And here is a thread discussing the reasoning for that: https://en.numista.com/forum/topic65420.html.
