 Spanish Cob Coins
Potosi Mint

Cob coins were minted at the Potosi mint from 1574 through 1773,  when they were permanently replaced by the machine struck milled bust dollar in 1773.  Interestingly, cobs continued to be struck at Potosi well after cob production ceased at the other colonial mints, and in fact, continued to be manufactured in parallel with the mints own machine struck milled pillar dollar between 1767 and 1770.  The mint began operations striking the shield type cob variety, but the famous 1640's Potosi mint scandal lead to a switchover from the shield type to the pillars-and-waves type cob in 1652.  Dates first appeared on Potosi cobs in 1617, but are seldom visible.

Certificates of Authenticity accompany all Potosi Cob Coins.

Shield type cob, Potosi mint, Philip II, assayer A, circa 1586-1589 (before dates were applied - the first appearing in 1617), graded fine / very fine for condition, nice full weight.  Lightly struck full cross with all lions and castles visible in the cross quadrants along with some peripheral legend .  Excellent full shield with all elements visible along with the mint mark "P" and assayer mark "A" at left, denomination mark VIII at right and some legend along the edge.  Coins of assayer A are not as common as most Potosi cobs and are significant in that they were struck during the time period of the famous defeat of the invincible Spanish Armada.  Due to the time period and typical high quality, assayer A coins are very popular with collectors.   Supplied with a New World Treasures photo type Certificate of Authenticity.

Shield type cob, Potosi mint, Philip III, assayer T, dated 162x (1620 per the cross side lion design), exactly like the 1620 coins salvaged from the Atocha, graded very fine for condition, possibly sea salvaged.  Excellent, nicely centered full cross with all lions and castles well detailed (quadrants transposed) and with digits 62 of the date 1620 visible between the 10 and 11 o'clock position along the edge (the 1620 date confirmed by the lion design found in the cross quadrants).  Equally nice, deep struck full shield with portions of the mint mark "P" and assayer mark "T" visible at left (the top of the P and left side of the T is missing but positive).  This coin is well struck for the time period and would make a great addition to any Potosí cob collection.  Supplied with a New World Treasures photo type Certificate of Authenticity.
