Ever see this overdate? 1393/1893

This is a cool overdate.
I can see screwing up and punching in a 3 in error then correcting it with the correct number.
But this one had the correct date and someone decided to re-punch this with the incorrect date over the correct one????

I could see the case where the correct 8 was on the hub but transferred to the working die weakly. The mint worker tried to grab an 8 punch to fix it, but accidently got a 3 instead. In other words, he wasn't trying to change the date, but he was trying to strengthen it.
Similiar phenomenon occurred on British Mint issues of the 19th century.
