| Reverse description | Bold Jerusalem cross with ornate terminals occupies the center of the flan, dividing the field into four quadrants. The mint mark 'P' for Potosí and the assayer's initial appear to the left and right of the horizontal arm of the cross respectively, with the date and denomination numeral '4' similarly positioned in the lower quadrants. A partial circular legend in Latin surrounds the cross along the clipped edge of the irregular cob flan, consistent with the hand-struck macuquina coinage of the Spanish colonial series. |

| Additional information |
Philip V reclaimed the Spanish throne in 1724 after abdicating in favor of his son Luis I, who died of smallpox just seven months into his reign. The Potosí mint was producing cob coinage — macuquinas — through much of this period, hand-struck on irregular planchets cut from silver bars. The transition away from cob coinage toward milled pieces was already underway in Mexico City but lagged considerably at Potosí, meaning this type straddles the final decades of a minting tradition that had run largely unchanged since the 1570s.
KM#30a specifically reflects the assayer transition at Potosí during these years, with multiple assayer initials known within the type.
