The Silson Period in Spratling Silver
For a few wartime years, some William Spratling designs were produced in silver plate by Victor Silson's company. They are real evidence of Spratling's commercial reach, but they are not the handwrought Taxco silver that should anchor the public collection.

How Taxco Silver Was Made: A Visual Guide to Its Techniques

Explore the techniques behind twentieth-century Taxco silver - from repoussé and chasing to champlevé enamel, stone mosaic, silver overlay, metales casados, and articulated handwrought construction - through examples from the Museum's collection.

Why Mexican Modernism Is Modern Art
Alexander Calder's jewelry was received as art the moment he made it, because he was already known as a sculptor. The Taxco school had no such advocate, and a half-century of mid-century Mexican silver has been miscategorized as vintage jewelry rather than what it is: modern sculpture.

How Rare Is William Spratling, Anyways?
Spratling is the most famous name in twentieth-century Mexican silver. Las Delicias was, in its peak years, the largest silver workshop in Mexico. None of that means his pieces are easy to find today. Across the 2,094 named-Spratling lots that have crossed a published auction since 2007, the median clears at $750, the top decile at $2,600, and only fourteen have ever cleared $10,000. Production was numerous. Survival is not.

The Value of Collecting the Taxco Golden Age
Taxco silver has beauty, history, scarcity, and market inefficiency in the same place. The auction record across 1,156 weighable Golden Age lots, with each lot's melt value computed at the silver spot in effect on the day it sold, shows the spread: a typical Spratling or Pineda piece clears at roughly ten times its silver weight, the best examples clear sixty to a hundred times, and the same makers' hollowware regularly sells below melt at the wrong auction. The drift between the metal floor and the recognition ceiling is the entire opportunity.

The Jill and Byron Crawford Collection at Bonhams
One couple's Taxco Golden Age jewelry, 119 lots across every major workshop of the era, cleared through two Bonhams sales in 2022 and 2023. The results are a cleaner benchmark for the middle of the market than collectors remember.

The Aguilar 990 belt that isn't in the Morrill book
A rare variant of Héctor Aguilar's iconic Georgia O'Keeffe-style concho belt carries a 990 stamp where every other surviving example reads 940. What the 990 actually means is an open question, but the auction record already recognizes it as something different.
