3. Bi-metallic 2 Euro and Edge Lettering ... by Frans Woons, Canada

The new euro coins show a variety of edges to help the visual impaired in identifying the coins. The types of edges found are: smooth (1 and 5 euro cent), a single groove around the coin (2 euro cent), coarsely reeded (10 and 50 euro cent), smooth with seven indentations (20 euro cent), alternating sections that are smooth and finely reeded (€ 1), and finely reeded plus incuse lettering (€ 2). This information and the report that some € 2 pieces show the "wrong" lettering made me look into the coin production process a little closer. In contrast to older coins (struck before the introduction of the screw press around 1500 A. D.), modern coins are struck in a collar (sometimes called "virole brise"; the other two dies being for the obverse and reverse of the coins). Because early coins were struck without a collar, they tend to be irregular in shape (so-called "splashes").

Coins with a smooth or straight reeded (either total or partial) edge can be struck in one operation. In those cases the inside of the collar is either smooth or (partially) grooved (vertically). Coins with edge lettering (incuse or raised) cannot be struck in a tight-fitting collar; the coin and / or collar would be damaged when the coin is ejected from the collar. A possible solution is a collar in sections (the so-called "virole brisé"). In that case the collar sections are moved apart just before the coin is ejected from the press. However, this is a slow process; too slow for modern high-speed presses.

So, how is the edge lettering applied to the € 2 coins? I don't know for sure but after some reading I came to the conclusion that it must be done before or after the obverse and reverse dies are applied (simultaneously).

First possibility: in many mints it is customary that coin blanks go through a "rimming machine" before they are struck. This machine reduces the diameter of the planchets a bit thus making them a little thicker at the edges (the "upsetting" process). During this process the edge lettering (or a groove as for the 2 euro cent piece) can be applied. This was customary in early American coins which were rolled between two dies ("cheeks") in a "Castaing Machine" (e.g., 1793 1 cent pieces with the incuse edge lettering ONE HUNDRED FOR A DOLLAR). Coins with raised edge lettering include Maria Theresa thalers of the Austrian-Hungarian Empire.

The second possibility is that the coin, after it has been struck, is rolled in an edge milling machine. This was sometimes done in the 18th century to produce coins with slanted grooves or similar pattern.

In conclusion, I think the production of the € 2 pieces is as follows (concerning the edges): First the blanks go through a rimming machine that produces the incuse lettering [e.g., in the Dutch coins GOD * ZIJ * MET * ONS * (God be with us)], second the coin is struck in a finely grooved collar producing the reeding.

For more information on coin making see the book "The Art and Craft on Coinmaking; A History of Minting Technology" written by Denis R. Cooper and published by Spink & Son, in London, England, in 1988.

6. The WBCC Bi-metallic Quiz Game #293 ... by Jack Hepler, USA
