Mapping the Madness: A Collector’s Guide to Mexico City Portrait 8 Reales Varieties

After years of collecting, researching, and uncovering new varieties, I’m excited to share what I hope becomes a living reference for fellow enthusiasts: a complete date-by-date breakdown of all known - and yet-to-be-discovered - Mexico City Portrait 8 Reales varieties. This is 8 Reales Madness in its purest form. Whether you’re hunting your first variety or your fiftieth, this list is here to guide, challenge, and maybe even inspire your next big find.

Ever since I started collecting Mexico City Portrait 8 Reales varieties about a decade ago, I’ve held a consistent belief: with every major design change - be it a new date, assayer, or monarch - there’s a high likelihood that existing dies were reworked by the mint’s die sinkers to reflect the update.

Mexico City produced millions of 8 Reales during this period, and knowing the approximate die lifespan of 20,000–30,000 strikes, it’s safe to estimate that anywhere from 50 dies in the earlier years to over 250 dies in the peak production years were used annually. Considering how labor-intensive die sinking was - and the fact that die steel was a scarce and valuable commodity - it makes sense that working dies would be re-punched or modified rather than discarded when changes occurred.

This idea has shaped how I collect. I’ve always kept an open mind that not all varieties are yet known - some just haven’t surfaced. And by following that principle, I’ve been fortunate to uncover a number of new varieties over the years.

This is a working set - still growing, refining, and upgrading - with each addition carefully chosen not just for grade, but for its place in the broader historical and numismatic narrative. If you’ve spotted a variety not listed - or think you’ve uncovered something new - drop a comment or DM me. Let’s document it together. Every new discovery helps complete the story.

Goals of the Set:

● Discover, document and display every date, assayer, and variety Portrait 8 Reales from Mexico City
● Prioritize eye appeal and provenance alongside technical grade.
● Encourage greater collector awareness and appreciation for the complexity of Mexican portrait 8 Reales.
● Eventually create the most complete and high-grade set of its kind.

This work is dedicated to fellow collectors who believe the hunt never ends. And that every coin has something to teach us.
