 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 in 1652.  Dates first appeared on Potosi cobs in 1617, but are seldom visible.

Certificates of Authenticity accompany all Potosi Cob Coins.

Mint:  Potosi
Assayer:  A
Weight:  27.3 grams

Price:  $895.00  SOLD

 

Shield type cob, Potosi mint, Philip II, assayer A, circa 1586-1589 (before dates were applied - the first appearing in 1617), graded extremely fine for condition.  Slightly double struck, nicely detailed full cross with all lions and castles boldly visible in the cross quadrants.  Excellent full shield with all elements clearly visible along with the mint mark "P" and assayer mark "A" at left, denomination mark VIII at right and ample peripheral legend including most of the King's name.  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 1620, sea salvaged - likely from the Atocha but no paperwork to positively identify it as such.  Using Mel Fisher's grading system, this would be graded as a high end grade 1 coin.  Excellent, perfectly centered full cross with all lions and castles well detailed and with bold digits 162 of the date 1620 visible between the 8 and 10 o'clock position along the edge (the bottom of the 0 is lightly visible at the 11 o'clock position and is confirmed by the lion design found in the cross quadrants).  Excellent, deep struck full shield with the mint mark "P" and bold assayer mark "T" visible at left (the P is struck backwards and looks like a q).  This coin would make a great addition to any Potosí cob collection.  Supplied with a New World Treasures photo type Certificate of Authenticity.

Pillars and waves type cob, Charles III, assayer (V-Y), dated 1768, grade fine.  A ruggedly handsome coin with bold features and in the shape of a bird.  Excellent deep struck full cross with all lions and castles at least partially visible and deeply struck.  Also visible on the cross side is the denomination mark 8 above, mint mark P at left, and 76 of the date 1768 below.  Equally nice pillars side details including the denomination mark 8, one mint mark P, SVL of the central PLV SVL TRA, very light Y of the assayer mark, and very bold 768 of the central date 1768.  When viewing the pillars side in its correct orientation, the coin has the interesting shape of a bird.  A very rugged, chunky, unique piece with nice weight.  Supplied with a New World Treasures photo type Certificate of Authenticity.
