Joseph Napoleon gold 320 Reales 1810-AI AU55 NGC, Madrid mint, KM545, Fr-300, Cal-54, Onza-1188 (Extremely Rare). Type with initials "AI" for assayers Isidoro Ramos del Manzano and Antonio Rafael Narvaez. Among Joseph Napoleon's rarest issues within his "De Vellon" coinage featuring the scarcer of two assayer combinations, whose borderline Mint State preservation is only surpassed by its appreciable mulberry-tinged honeyed golden patina and residual flash. Gentle, uniform wear precludes the current specimen from finer technical designations, but as it stands, remains a hotly contested issue bested only by the Paramount specimen, offered in 2021 as an AU58.
