Designer
Edmund J. Senn
The El Paso sculptor who shaped one of America's rarest coins — and was left off it.
In the summer of 1935, an out-of-work sculptor named Edmund J. Senn worked in a coin dealer's garage in El Paso, pressing another man's idea into plaster. The result was the Old Spanish Trail half dollar. Senn's hands made it. His initials never touched it.
Who he was
Edmund J. Senn enters the record at a single moment — and almost vanishes the instant it passes.
In 1935, a strong-willed El Paso coin dealer named Lyman W. Hoffecker wanted a commemorative half dollar to mark the 400th anniversary of the explorer Álvar Núñez Cabeza de Vaca's wanderings across the American Southwest. Hoffecker had the idea, the political muscle to push it through Congress, and a clear picture of what the coin should show. What he did not have was the skill to model it in three dimensions.
He looked east first. By his own account, Hoffecker approached established sculptors — but each wanted too much time, and each wanted the freedom to change his design. Hoffecker wanted neither. So he hired closer to home: Edmund J. Senn, a local sculptor who, in the depths of the Depression, was out of work and on relief. Senn set up in Hoffecker's garage, and Hoffecker, he later admitted, stood over him while he worked.
That is nearly the whole of what survives about Senn. Numismatic references describe him only as "an El Paso, Texas sculptor" — no birth or death dates, no record of his training, no list of other coins or monuments. He is remembered for one job, done well, for which he received no credit on the object itself.
The craft
To understand Senn's role, you have to separate two jobs that newcomers often blur.
The designer decides what a coin shows — the cow's head, the yucca, the curving line of the trail. The modeler (or sculptor) turns that idea into a large plaster relief, the master from which the Mint cuts its dies — the hardened steel stamps that strike the coin. The design is the thought; the model is the object. Senn was the modeler.
The design was Hoffecker's, and it leaned on a pun. The obverse — the heads side — carries the head of a cow, because cabeza de vaca means "head of a cow" in Spanish. The reverse — the tails side — sets a blooming yucca over a map of the old trail across the Gulf Coast states. Senn's task, working in mid-July 1935, was to take those ideas and sculpt them into relief convincing enough to mint.
It was not a free hand. When the federal Commission of Fine Arts — the body that reviews U.S. coin designs — examined Senn's first models, it objected to the look of the cow's head and to the way "LIBERTY" sat on a riband. Senn reworked the models, though in the end little about the head changed. He was executing a vision, under a watchful client, against an official critic. That he produced a coin collectors still prize speaks for the skill in his hands, even if the historical record gives him almost nothing else.
The credit went elsewhere. The initials on the coin are LWH — Lyman W. Hoffecker's — tucked at the lower reverse, to the right of the 1935 date. Senn, who only carried out Hoffecker's design, signed nothing. Catalogues today often list the two men together as the coin's engravers, a small, late correction to a name that was once left in the garage.
What we know — and don't
This is a short page on purpose. Beyond the Old Spanish Trail commission, almost no biographical information about Edmund J. Senn is publicly documented — no dates, no training, no other known works, no portrait. The standard numismatic histories of the coin mention him only in passing, in Hoffecker's own telling. We have set down here exactly what is verifiable and no more. As more comes to light — a census record, an El Paso art notice, a second commission — this page will be expanded.

Questions collectors ask
Did Edmund J. Senn design the Old Spanish Trail half dollar?
Not exactly. The design — the cow's head, the yucca, the trail map — was the idea of coin dealer L.W. Hoffecker. Senn was the sculptor Hoffecker hired to turn that idea into the plaster models the Mint worked from. He executed the design; he did not conceive it. Catalogues today often credit both men as engravers.
Why aren't Senn's initials on the coin?
Because the design wasn't his. The initials a coin carries usually belong to whoever conceived the design, and that was Hoffecker — his LWH sits at the lower reverse, to the right of the 1935 date. Senn, who only carried out Hoffecker's plan, signed nothing.
Who was Edmund J. Senn?
An El Paso sculptor who, in 1935, was out of work and on relief when Hoffecker recruited him to model the coin in his garage. Beyond that single commission, numismatic sources record almost nothing — no birth or death dates, no training, no other known coins. He is, in effect, a one-coin figure in the record.
Why does the coin show a cow's head?
It's a visual pun. The commemorative honors the 400th anniversary of the explorer Álvar Núñez Cabeza de Vaca, whose surname means 'head of a cow' in Spanish. Hoffecker chose the image literally; Senn sculpted it.
How rare is the coin Senn modeled?
Very. Only 10,000 were struck for sale (plus a handful of assay pieces) at the Philadelphia Mint in 1935, making the Old Spanish Trail half dollar one of the lowest-mintage U.S. commemoratives and a long-sought key for collectors of the classic commemorative series.
