Attribution Notes 

• Dating and locating a cob can be difficult.

• Mint marks and assayers’ initials are important attribution clues.

• If an assayer’s initials are present and the mint is known, dating parameters may be narrowed.

• Differences in mint marks and assayer initials are notable collectible features.

• One of the challenges in identifying cob coins is their crude appearance and irregular shapes, often further affected by clipping, which can obscure key design elements.

Royal Cobs 

• Royals stand apart from regular cobs due to better quality.

• They are round, more carefully struck, and better centered than standard cobs.

• They are described as presentation pieces or proofs of minting quality rather than regular circulation coins.

Authentication Notes 

• Attribution can be difficult because of irregular shape, uneven strikes, and incomplete details.

• Mint marks, assayer initials, and visible design elements are the main diagnostic clues.

• Monetary reforms incorporated dates, mint marks, denominations, and assayer initials to establish more regulated minting practices.

Market Note:​

Given the extensive circulation and historical importance of Spanish cob coinage, replicas can be found in the market. Collectors are advised to proceed with caution, particularly when listings do not clearly state this and the goal is to obtain an original piece. These replicas may or may not be made of silver, and they often lack the natural characteristics typically seen in genuine examples.
