cf. KM-17A; Cal-Type-279. Weight: 13.73 gms. Though this Potosi cob does not show its date or assayer mark, making its precise attribution impossible, it does retain much of the monarch's name, denomination mark, and charming castles and lions. The noted environmental damage is mostly limited to the peripheries and the coin presents handsomely overall. To view all items from the Pat Johnson Collection, click here.

Lot description:


BOLIVIA. Duo of Cob 4 Reales (2 Pieces), 1598-1621. Potosi Mint. Philip III. Both PCGS Genuine--Environmental Damage, VF Details Certified.
A rather intriguing pair of 4 Reales cobs. Despite the noted environmental damage, both coins present a striking dark toning, one with highlights of golden iridescence. The first coin presents curiously blundered assayer and mint marks, and is sure to reward an inquisitive collector. The second is struck on a broad flan that reveals large segments of the name and titles of Philip III.

Lot description:


BOLIVIA. Cob 4 Reales, ND (1651-52)-P. Potosi Mint; Assayer Antonio de Ergueta (E). Philip IV. NGC VF-35; Countermark: AU Details.
KM-17B; Cal-Type-279. Weight: 13.48 gms. An intriguing Cob with much individuality and originality. Although this is certainly a 4 Reales piece, its obverse was struck with an 8 Reales die. The unmistakable numeral "8" appears above the assayer's initial to the right of the Habsburg shield. On the left of the shield, a bold "crown alone" countermark appears. The reverse shows some flatness and does not retain any of the peripheral legends, but shows well-struck and handsome castles and lions. The coin presents sharp details and wholesome surfaces, deeply toned to a beautiful pewter gray. A VERY RARE coin in this condition, almost certainly unique with this mismatched obverse die. Exceptionally interesting and attractive. To view all items from the Pat Johnson Collection, click here.

Lot description:


BOLIVIA. Cob 4 Reales, ND (1649-51)-P. Potosi Mint; Assayer Juan Rodriguez de Rodas (O). Philip IV. PCGS Genuine--Salt Water Damage, VF Details.
KM-17B; Cal-1107. Weight: 13.26 gms. This salvaged cob displays satisfying detail despite its noted saltwater damage. The obverse shows a mintmark, denomination, and identifiable assayer's marks. The reverse is more impressively preserved, with sharp castles and lions, albeit overstruck with the crowned "L" stamp that indicates a devaluation. Most pleasingly, the final two digits of the date appear on the rim, truncated but unmistakable. An appealing example of this RARE issue, with abundant detail to admire.

Intriguingly, the date uses an Arabic numeral "5" instead of the typical Spanish 5. From our research, it appears that this more modern digit was used only occasionally in the two years of assayer Rodas' tenure, as under the succeeding assayer "E" (and the subsequent coinage reformation beginning in 1652) usage reverted to the traditional Spanish 5. The Arabic 5 was not used again widely in Spanish colonial silver issues until 1755, over a century later. To view all items from the Pat Johnson Collection, click here.
