SPAIN. 4 Reales, 1863/2. Madrid Mint (6-pointed star). Isabel II. NGC Unc Details--Excessive Surface Hairlines.
KM-608.2. Overdate variety. Despite the noted hairlines (which don't appear to be as "excessive" as described), this example is free from wear and even offers some subtle cobalt and lilac toning nearer the peripheries.
