Is this a pirate cob?

I am really not sure what to call this. A pirate coin or a cob?
I think that cob refers to a silver piece of 8. This one is way out of my collecting interests. It has cleaned up a bit to the point that I can read some of the details. I see a Vlll with an 8 on one side. And a date of 164_, Then it looks like it was counterstruck with a date of 168_ on the other.
Does anyone have any ideas or able to lead me to a reference?
Weight is 5.2 grams
Diameter 23mm

When I bought this in a little lot at the flea market, I could barely make out the large 8.

Philip IV Æ 8 Maravedis

 

Thanks Mat. So those are counter stamps then?
What is the value of one of these? Maybe $5?
Thats what I paid for three ancients, at least the other 2 are ancients.

 

Yes and as for the value, probably, since it's corroded. If it was in better shape, about $30.

 

Looks to my old eyes to be dated 1691 on the counter stamp.8i

 

FYI, here's an 8 reales cob, 1626, Potosi, Philip IV:

 

I kept trying to look for the Cross, I din't realize I was ;ooking at a shield when I first got it.
Nice Cob Robin.

 

It went back into the olive oil, I have been having good results with a flash of Acetone after the long soaks in distilled water and a virgin oil.

If anyone has another method, please let me know.
