Help IDing possible colonial coin? or token?

[RayLJ]

I found this mysterious coin or token while metal detecting in the lowcountry of South Carolina today. This is an area where we have found early colonial coins and relics in the past (georgivs II rex farthings, Hibernia half pennies, Spanish reals, etc.). This one is really making me scratch my head though!

It appears to be made of copper and is fairly large - approx. 28-29 mm across.

One side appears to have two marks - one in a depressed circle with roman numeral "XII" and one non-depressed with another roman numeral.

The opposite side has a depression with some other symbol or possible roman numeral inside. I am attaching a partial drawing of this symbol as best I can interpret it.

Any help identifying this mystery item would be awesome!

The XII may mean that it's a shilling. There were 12 pence in a shilling, which could explain the XII on the coin.

Super find! Looks like a Spanish Maravedis cob. Here are Tnet threads about a couple others:

Shillings are silver coins. There could be no coin made of copper that would equal 12 pence unless it were huge!! They didn't make coins back then all of one cheap alloy and whimsically put a denomination on them as we do here these days. The old coins were made in a value of metal just like ours were when we had the gold and silver standards.
