A look at the work behind Denver's coins
The news: The U.S. Mint released its Faces of the Mint profile of Jolene Martinez on September 25, 2026. The Mint calls her an electrical industrial controls mechanic at its Denver plant. She helps keep the site and its machines running.
Collectors often first meet a mint through its coins: a loose roll, a boxed set or a piece for a collection. This profile turns to the work behind those coins. Presses need care, but the building and its other systems need care too. Martinez's story puts a name and a job to that side of coin making.
What Martinez describes
In the Mint's video, she talks about machines, communications lines and safety systems. A machine problem comes first, she explains. The job can reach beyond the presses that strike coins. Other parts of the site also need work to keep the plant running.
She also tells how she moved from counting and bagging coins to an apprenticeship in plant engineering. That path took her from handling the coins to helping care for the equipment used to make them. She says those trade skills have value beyond her work at the Mint. Readers can hear her account in the linked video.
The Mint's written Facebook caption for this profile describes a nearly 28-year career at Denver. It also notes her work as a journeyman and her union leadership. A journeyman is a trained worker in a skilled trade. The Mint says she spent more than two decades as the only woman in those skilled trades shops.
Her job title describes care for the controls that help machines work. The profile does not identify her as a coin designer or an engraver. It is about keeping the site working. It is not an announcement of a new coin, a new design or a change to how all Denver coins are made.
Why Denver matters to collectors
The Mint's Denver facility page lists the site's main jobs. It strikes coins for use in change. It makes coin dies, the metal tools that stamp a design into a coin. It also makes collector items, such as annual uncirculated sets, and commemorative coins when Congress allows them. Coin production at the Denver site began in 1906.
These jobs give collectors a reason to care about the profile. A coin design needs more than an image on paper. It also needs tools, a press and staff to keep the work going. Martinez's story points to one part of that larger team. The video does not say that she makes every coin or runs the whole line.

Look for Faces of the Mint: Jolene Martinez on the verified USMINT YouTube channel. Open its full description to see September 25, 2026. That is the video's publication date. There is no verified exact posting time to add to it.
The Denver page links to tour details and other official videos. They offer more background on how coins are made and the places where that work takes place. This short profile is a look at one worker's role. It is not a guide for fixing a machine or a notice of a change in coin production.
About the photograph
Larry D. Moore took the Denver Mint exterior photo on July 17, 1987. It shows the site as it then looked. It does not show Martinez at work. The old photo also does not show how the building looks today; the caption identifies it as historic context.
CoinHub's report on the 2027 Working Dogs commemorative designs looks at a separate coin program. It may help readers compare a design announcement with this employee profile. One focuses on what a coin will show; the other on the work behind making coins.
