Founded in 864 by Charles II, the Monnaie de Paris – France’s official mint – is the nation’s oldest institution and one of the world’s longest-standing companies. The mint was Paris’s first factory and remains one of the few still in operation today. The Monnaie de Paris enjoys global recognition for its expertise, striking coins for 40 different countries worldwide. In 1973, the company opened a new French factory in Pessac.

The Pessac facility is responsible for manufacturing euro coins for circulation in France, as well as minting foreign currencies. It manages the entire production process, from cutting the blanks (pieces of metal that are shaped and weighed before being transformed into coins) to packaging the final product. Every year, over 1.6 billion circulating coins are minted at Pessac, with two-thirds destined for export.

Why is it important to preserve this heritage?

In light of the Monnaie de Paris’s mission – “To share the currencies of yesterday, to create the currencies of today and invent the currencies of tomorrow” – safeguarding its heritage has naturally become a central priority. With a collection of 300,000 objects, the institution is the guardian of priceless tangible and intangible assets.

The Monnaie’s factory at 11, Quai de Conti in the French capital hosts the Musée de la Monnaie de Paris, a mint museum dedicated to the art of metalworking. This one-of-a-kind experience combines exhibition spaces with a glimpse into some of the factory’s workshops. The exhibition route explores a wide range of disciplines (including art, science and technology, the history of peoples, taste and economics, as well as archaeology and sociology) that reflect the richness and diversity of the Monnaie de Paris’s collections and celebrate the men, women and professions that uphold its exceptional craftsmanship.

Everyone is free to explore the museum’s collections online and even visit virtual exhibitions thanks to a digital portal dedicated to the museum’s historical holdings (which are growing year after year).

This first digitisation campaign will focus on the tools used in jeton production (also known as dies) under the Ancien Régime. The primary aim of the project is clear: to showcase the museum’s holdings – and the first step in this process is to upgrade the institution’s online portal. There is a second objective: to launch a dedicated digital platform, in partnership with the BnF, that will present the tools used to manufacture jetons alongside the tokens they produced, as held in the National Library.

Contract for digitising artefacts in situ

Following the contract awarded to Arkhênum, the company is tasked with digitising the complete set of Ancien Régime jeton-making tools over a three-year period. The aim is to digitise all 4,500 objects that fall within this category.

The initial phase of the project, set for 2025, will focus on digitising the first 1,500 dies, and will generate 5,000 digital views. Each tool will be photographed from three angles: axial, three-quarter and side view.

Our on-site team will set up a custom-built photographic studio on the Pessac site, which is home to the entire collection. This will consist of:

  • One Phase One digital camera, which will be used to capture axial shots of the impression.
  • One ScanCube scanner for 2D imaging with optimal lighting thanks to its reflective panels.
Our two photographers – Stephanie and Tom – will respect the site’s specific working conditions (designated working hours, protective footwear and safety vest, strict access protocols, etc.).

The technical hurdles

The special characteristics of these objects means that our experts will need to devise targeted solutions to address different aspects of the imaging process. They will be required to:

  • Document the materiality of the objects by capturing all the details and markings, including on the secondary sides of the tooling.
  • Capture axial views (of impressions), a three-quarter view, and – where necessary – an additional side view to reveal any inscriptions that are absent from the three-quarter shot.
  • Factor in special cases for dies coated with varnish or grease as well as polished dies, where colorimetry or lighting will be required.

Additional refinement will also be called for during post-processing, which will take place in the Arkhênum workshops:

  • Centimetre scale embedded onto the cropped image
  • Embedding of the object’s inventory number

What does 2026 hold in store for us?

In 2026 and 2027, the teams at Arkhênum and the Monnaie de Paris will work closely together to digitise the entire inventory of 4,500 Ancien Régime jeton dies.

This project to digitise coining dies is a first for Arkhênum, which has traditionally focused more on digitising coins. It is an exciting challenge for our technical and R&D teams to test the limits of existing and future technologies as well as our production processes.

True Life in God: an AI-enhanced project

MEMORIST, in partnership with its subsidiary Arkhênum, recently undertook a project for the Swiss foundation True Life in God. From analysing the foundation’s requirements to digitising its collections for hosting online, this large-scale project required end-to-end support, tailored to integrate proven heritage digitisation technology with cutting-edge developments in artificial intelligence (AI). Digitisation took place in situ on MEMORIST’s premises in Geneva.

With a solid understanding of the foundation’s needs and having assessed the project’s challenges in detail, our team proposed an AI solution to enhance the data available and make collections easier to access and explore online.

With this project – and similar initiatives carried out for other clients – MEMORIST and Arkhênum joined the 18% of companies using AI in production environments.

HTR-enhanced heritage digitisation

Initially, the team focused on digitising a selection of heritage assets, including handwritten notebooks, press reviews and artefacts. Using the latest breakthroughs in AI, Arkhênum’s experts employed automatic handwritten text recognition (HTR) to “read” 125 manuscript notebooks authored by the founder of the True Life in God Foundation – Vassula Rydén.

This was no mean feat: Rydén’s handwriting is characterised by a distinctly vertical style, with prominent ascenders and deep descenders.

As part of the feasibility analysis, the Arkhênum R&D team compared various AI solutions to identify the best fit for processing this type of contemporary document.

After finalising the selection, our experts optimised the software processing in several phases, fine-tuning the parameters to obtain maximum output quality, and ultimately achieving an optimal character recognition accuracy rate of 98%.

AI optimises HTML data retrieval services

Under pressure to retrieve content from a soon-to-be-decommissioned website, the Arkhênum R&D team took a fresh look at the objective. The client’s request was clear: to recover the locations and dates of all 1,176 talks given by Rydén worldwide and import this data to the digital library then under development.

However, analysis confirmed that conventional algorithms could not recover the data accurately, so the team turned to AI once more, writing a custom script to scrape the data from the HTML pages and convert it to a standardised ISO format using an Excel table.

They also used AI to standardise event times, display country flags in ISO format, and translate the town and country names to English.

Thanks to this approach, the resulting content was 99% reliable. The three errors detected were attributable to the website itself and not the AI-driven processing. The content was subsequently imported into the Limb Gallery digital library.

Building open archives for True Life in God

With this project, the foundation aimed to share Vassula Rydén’s work. A speaker, author and painter, the digitised archives include around fifty of the founder’s paintings, highlighting her personality and development.

Arkhênum deployed its Limb Gallery digital library solution to showcase the foundation’s archives online.

This platform, which aggregates the archives available from different online sources, will be regularly updated with new resources, including inventories.

With its keyword search capability, the platform is an invaluable tool for researchers and writers keen to explore the manuscripts, 2,228 press clippings and talks.

In addition, AI technology is evolving so quickly that it will soon be possible to optimise how search results of handwritten texts are displayed, with key words and phrases automatically highlighted – functionality that, for now, remains out of reach.

Future opening of a physical museum

In addition to the True Life in God archive website, which provides 24/7 access to resources from many sources, the foundation is already laying the groundwork for the next phase: opening a physical museum in Sweden where visitors and researchers will be able to study the archives or consult publications.
