A tiny mint in Switzerland is on the cutting edge of technology with
its latest release.
The Helvetic Mint, a private company that calls itself “the coin
factory,” has released a three-dimensional diamond-shaped coin.
The upper portion of Niue’s 2016 .999 fine silver $2 coin has 32
facets plus the “table” bearing the Ian Rank-Broadley effigy of Queen
Elizabeth II, and 24 lower facets. A real diamond (0.1-carat Top
Wesselton Si1 Brilliant Cut) is attached to the coin as well.

The coin was released publicly on June 6, with delivery to clients
the following week.
Each coin has a lasered serial number on a lower facet and the
matching number on the certificate of authenticity. The diamond coin
is presented in a special hexagonal wooden box with LED light inside.
The Helvetic Mint’s Sabine Meyer developed the project for one year,
with actual technical production requiring six months to meet the
technical challenge, she said.
“We are a small company working with traditional and modern skills,
but extremely creative and always interested to develop technical
[skills],” she said.
The coin is struck from one solid piece of silver.
The most challenging part of striking the coin was to create and
maintain the pinpoint sharp tip of the diamond-shaped coin and the
sharp edges of the facets. It required a very slow increase to
striking pressure, Meyer said.
She could not disclose the number of collars required to strike the
multifaceted coin, calling it a “technical secret,” but obviously it
was more than for a standard (mostly) flat coin.
Once the coins were struck, they were satinated (with the
application of an undisclosed substance to give the coins their satiny
look), which also threatened to compromise the sharpness of the facet
edges, Meyer said.
The coin weighs 44 grams and measures 26 millimeters in diameter at
its widest point and 17 millimeters in height.
It has a mintage of 222 pieces.
No United States distributor was named by press time June 8.
