World Money Fair Technical Forum 2022 – a Review (Part 1)

As with the World Money Fair Technical Forum in 2021, the 18th event held earlier this year was also held virtually. This year it comprised 11 presentations over two days, hosted by Dieter Merkle of Schuler and Thomas Hogenkamp of Spaleck.

In this issue of Coin & Mint News™, we cover five of those presentations. In next month’s issue, we will follow up with the second half of the Technical Forum.

New Technologies for Manufacturing Complex-Shaped Coins

Aziya Ibrayeva of the Kazakhstan Mint described with new technologies developed to manufacture commemorative coins with complex shapes.

The first, ‘UNOVYS’, produced in 2021 for the National Bank of Kazakhstan, has a convex/concave configuration, making it difficult to obtain low relief engraving, the challenge being to guarantee its durability. The protruding relief on the coin was achieved using laser engraving.
