Watch List notes:

Guatemala, "moclon" 2 reales, crown countermark (1662) on a Potosi, Bolivia, cob 2 reales, Philip IV, (1651-52)E, struck from 1R dies (unique). CT-Type 175. 5.96 grams This fascinating coin started life as a 1R on a very oversized and overweight flan but then was confirmed as a 2R by virtue of the countermark (fully visible in the center of the full cross-and-tressure), the denomination error most blatant on the obverse, where nearly full legends enclose a full shield with clear P-E to left and I-E to right, toned AVF with stripped hole at one end of cross and neater hole to right of shield.
