The real cobs do get clipped down to their 26gram weight or close to it as possible. The result may be crappy looking but it does give this form of money a little genuine character that makes it descriptive for the era. Eventually the coining mill and coin dies came around raising the minting rate and quality of the Spanish 8 Reale.

Nowadays, the quality bar is high and the eight reels can be minted precisely.
Clipped coins bring back a time when Silver could be heard jingling in pirates pockets !😇😊
