Here is a beautifull 8 reales, minted in mainland Spain in Valladolid around 1565 (or a bit later)
Essayer A (inverted V) with a little ring over it.
The Valladolid mint mark is made of 3 waves here on the right - bound by 3 dots in a triangular shape above and bellow it.
Calico 277 - those with the book or the PDF can check it out, there is a surprise :)



Hope you like it, we don't see much mainland cobs here (mostly due to the fact that most readers are from America and collect new world cobs)
