Star R error in 5ptas 1957?

Hey, hope all is going good. Is this a error or it is erased or something? Or its a factory error?

Franco's nickel 

I think it is just a regular worn out Spanish Mint symbol, nothing out of the ordinary

OP's Coin:

N#781

Looks like a worn coin to me. What do you think is the error or what part is erased in your view?

No error.  On the star is 62 since it was minted in 1962.
