Authenticity of 5 lira Italy coin

I have  Italy 5 Lire 1927 coin N#4047 , KM 67

Both sides are looking good , the weight of the coin is ok , but the edge is different . It does not have required lettering.

What can you say about its authenticity ? Is it indeed fake or something was done with its edge?

Thanks

You must know that this is one of the most counterfeited coins of all time.

Edge is difficult to replicate for counterfeiters. This is a counterfeit obtained by pressing two molds together. Edge is a great way to identify counterfeits, especially silver coins. 

This coin may actually have some silver in it, but is a homemade one, not a mint struck. I think it is not expensive too. 

Thanks to all for the answer, as I suspected,  I agree that it is a fake..
