Spanish Cob for ID please

[bigjerryok]

Could anyone please help ID this Spanish cob? (I assume that's what it is!) Coin is about 2cm across. Many thanks in advance. And can you point me at a website that helps to ID such coins. Many thanks in advance.

Looks like an Atocha 1622 era cob to me.

What's Mackeydon say? It looks authentic from my view which is nice as we see a lot of fakes and copies here.

My guess: It's authentic: BOLIVIA. Cob 8 Reales, ND (1578-95)-P B. Potosi Mint. Philip II.

PS: Its denomination can be determined by its weight; using 27.5 grams for an 8R coin. This coin might be less than that of an 8R.
