Silver 8 real of Philip II of Spain dating to 1556-98. The flan is irregular in shape and is fairly thick. Due to the irregularity of the flan shape most of the legend is missing. In the mid-16th century major silver deposits were found in South America, in 'Peru'. This relates to an area much larger than modern day Peru. Coins minted from here were called 'cobs' (cabo)- rather than producing a nice flan onto which the image was struck, cobs were simply a bar of silver cut into appropriate weights (2, 4, 8 reals) and they are obviously of odd, irregular shapes. This coin was most likley minted in Peru due to it's irregular shape.
Reverse description: Scallop shape with images inside- possibly a lion and a castle. The scallop is split into 4 by a cross.
