It has been stamped twice, first to “8 Maravedis” in 1652 and later, in 1658/59, back to “4 Maravedis”.
It is a nice coin since they did not hammered the coin before applying the stamps.
It was common to use coins of “2 Maravedis” , hammered to have the size of a “4 Maravedis”, and then stamped with the “8”.
