Your cob is a 4 reales, struck in 1751, at the Potosi (Bolivia) colonial mint. It should weigh in the neighborhood of 13 grams.Nice Cob you recovered and welcome aboard to Treasure Net!
Thank you so much for your expertise on this coin! I have learned quite a bit!Your cob is a 4 reales, struck in 1751, at the Potosi (Bolivia) colonial mint. It should weigh in the neighborhood of 13 grams.
The details on your cob give us the info we need to i.d. this coin. Not all die details show up on cobs, but enough is present on yours. (please see attached pic)
The design on your cob is the "Pillars & Waves" design adopted at Potosi in 1652, & used until the end of cob production, in 1773. Lima, Peru also used this design from 1684 through 1752 ...
NOTE: This design was never used on 1/2 reals of any Spanish mint. 1/2 reals always used a stylized monogram of the king's name (in Latin), & never used this design. (Early Mexico 1/2 reals used a similar design, but was discontinued in the later 1500s, in favor of the stylized monogram)
..would really like to see the cross side of this cob, if it's not too much trouble ... it'll have pertinent details also ...
Hope this info helps...great find!View attachment 2240130View attachment 2240131
