Lending us material
The material of NOMISMA is made from photographs of real specimens alone. Having decided that, the pieces we do not hold ourselves can only come from those who do. That is why I am writing to ask.

After a career in finance, he still works in asset management consulting and in buying and selling antique coins. He teaches how to handle money and physical assets from the standpoint of building assets, using them, protecting them and passing them on to the next generation. At NOMISMA he extends the methods of checking real objects and historical sources into learning that thinks about history and about life today. The operating company, Convoy Switch Inc., holds a secondhand goods dealer permit (Fukuoka Prefectural Public Safety Commission No. 901032010105). The founder buys and sells coins at this company. For that reason NOMISMA issues no authentication, valuation or price opinion on any individual coin. Nor does it recommend buying or selling any individual item. Historical prices and market institutions are treated as subjects of study.

What we ask for
Three things. Whichever of them you can spare is enough.

Images
Obverse and reverse. What you already have is fine; we will not ask you to shoot again.

Measurements
Diameter, weight, die axis. The figures alone already make material.

Readings
The inscription as read, and a note of what cannot be read.
What comes back to you
A piece you lend us leaves the following behind.
- Every place it appears names the holder and the photographer.
- Every relevant term (461 of them) and course (68 courses) links to that piece.
- It is published in 7 languages.
- It joins the coin and banknote gallery (436 at present) and is given a page of its own.
What it costs you
We take on as much of the work as we can.
- No writing required
- We write the description. Before publication you see where it goes and what it says.
- One piece is enough
- There is no minimum. A single coin already makes material.
- A fixed term is fine
- Tell us to withdraw it and the passage comes out.
