Watch List notes:

Santo Domingo, Dominican Republic, copper 4 maravedis, Charles-Joanna, mintmark oP-oS (very rare), assayer to left not visible (F), denomination o/IIII to right. S-SD1; CT-unl (Type 134). 3.37 grams. Broad-flan VF with much legend, central weakness and slight surface porosity, but with bold full oP-oS for mintmark (backwards S), the first we have seen with the o's above the P and S, no doubt an earlier variant as several letters in the legend are Gothic and the columns are actual pillars, not stylized like on the normal coppers.
