The World Money Fair is the world’s largest coin fair. This year’s event, held 30 January to 1 February, attracted more numismatics enthusiasts than ever before – with over 13,600 attendees and more than 300 exhibitors from 50 countries present. WMF Director, Goetz-Ulf-Jungmichel, commented that the event ‘shows that our industry is not only preserving history, but actively shaping the future’.

Germania Mint unveiled a new special release coin for the recent World Money Fair, featuring Black Light Colours technology.

Interest in precious metals investments continues to grow – attributed in part to investors, both experienced and novel, turning to these products as a safe and secure method of investment. Authenticity and trust generation are particularly important to Sigma Metalytics, a family owned and operated business based in California, USA, that offers precious metal verifiers to individuals and mints alike.

Titled ‘The Future is Here: How Artificial Intelligence Will Change Modern Minting’, the webinar was hosted by Aditya Berlia – an entrepreneur, educator, and AI advocate – and sponsored by Carveco.

Beside cashless payments, coins are still a part of modern life. Minting, circulating and recirculating of coins remains a great responsibility for mints and central banks. Depending on the quality of the coin, the lifespan of hard cash can be 10 years or more.
