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.

8 Reales

Item#: 10004
Denomination: 8 reales
Mint: Potosi
Assayer: B
Weight: 27.1 grams
Diameter: 1.5-1.6 inches

Price: $595.00 BUY ITEM

Shield type cob, Potosi mint, Philip II, assayer B, circa: 1576-1578 (prior to when coins received dates), graded choice fine, very light and even toning. The eight reales denomination was first issued at Potosi in 1575, so this is a very early issue coin. Early issue coins were noted for their high quality and were struck on broad full flans. This coin is well struck and has nicely centered details. The cross is choice with nice lions and castles. The lions are of the small rampant type found on the earliest issue coins of B, C, and L. The shield side includes a full shield with all elements well struck and with the mint mark P and assayer mark B at left (the bottom part of the B is lightly struck but visible). An impressive early issue coin.
