KM-40 variety, Ferdinand VI type.  Struck at the Potosi mint. 25.3 gms.

We don’t list many cobs, because frankly they are usually ugly, unoriginal, dull gray things that don’t really fit with what we do here.

But this one is incredibly striking, with original coin gray surfaces, dramatic violet, cobalt blue and golden orange toning in the devices and a look that has CRO written all over it.

This coin is from the CRO archives and is not currently available for sale.
