What it is
A detailed guide to the silver reales 'treasure' coins recovered from the 1622 fleet wrecks Atocha and Santa Margarita — how the coins look when found, how they are cleaned, conserved, and graded, their 17th-century values, and how to identify mint, markings, and assayer.
Why it matters
It ties specific coin types to the two most famous 1622 wrecks and gives the current assayer identity and timeline for the Potosí, Lima, and Mexico City mints up to 1622 — the attribution backbone for any Atocha-era cob.
Who it's for
Collectors and specialists who own or are researching Atocha/Santa Margarita silver and need assayer timelines alongside the wreck context.
