Hello everyone - can you help on this one coin from Chile

this looks like die clash ,in some areas looks like it  is a repunched plan from a weak strike..thank you

That's a very interesting coin.

The letters on the second image, are look incuse, are they?
It looks like the letters "REPU", in reverse and upside down.

So to me it looks like the coin you have may have been stamped with a coin, rather than the die, and then restamped with the die. So you have a (mirror) image of the coin's obverse on your coin's reverse.
(Sorry I don't know the correct terminology here, but hopefully I'm clear enough in what I'm saying)

Basically, I think your coin has been struck twice, the first time had the previous coin stuck to the die, the second strike was with just the die.

thank you it clears up a few ideas i was having ,,,thanks
