Found my first silver cob in VA last week, any help determining age is appreciated. It is a shield type and a P and R are clear on the coin, but I do not have enough experience with these cobs to know if those are assayer initials or mint marks, or both. Any help is greatly appreciated!
May be Potosi Peru (now Bolivia) mint, cob, Philip III, Assayer R.
Denomination can be closely determined by weight using 27.468 grams as a reference for an 8R coin; proportionally less for a 4R, 2R, and 1R.

Wow,
She is a beauty !!! Fantastic find...
It is Potosi and looks like to me P over full ToverR, that would tell you 1643-1648 Pedro Trevino and according to Sedwick's Practical Book of Cobs.
Magnum, your now hooked, get Sedwick's Book, it is a must have if you find more. The Practical Book of Cobs.
Many Congrats on such a splendid find, Excellent. By the way the man who minted your cob was put to death for his shabby workmanship. NICE !!!!
Realeswatcher could tell us more...but I see small dots separating the mint and assayer as well as below the denomination to the right of the shield, these are clues to further narrow the date. More clue's to use are the lions and Castles on the reverse of the coin, they are not "furry" full lions. The Castles are a bit different also. Looking into a few more books, this could be earlier...maybe even 30s. What's the weight?
Cobs are fascinating...again Congrats.
