Need help with Peru 1/2 dineros

I purchased these from a few different sellers over the past few years and after looking at all of them again together I am not sure if they are all authentic or not. There seems to be a reoccurring die crack and strange denticle theme going. I could use some help identifying them and the possible varieties if they are authentic.

Looking at others online, I believe they are authentic. Not sure why someone would counterfeit them, though? Hopefully someone else will chime in with more knowledge than me.

I think he wants to know if they are "original." My TV show just started. Until tomorrow...
Is it possible these are restrikes?

Look good to me too! The ANS has several of the original dies from this series, some of which are well-shattered.

Those are all genuine. Keep in mind blazing UNC examples of these Peruvian dimes are readily available for a lot of those 19-aughts and -teens dates (you have some examples there), so in this case, it's nothing to be suspicious of. Not sure why exactly so many UNCs exist... clearly there were more than needed for small change circulation.
