Dubbeltje

 ( Coins Of The Netherlands ) 

A dubbeltje () is a small former Netherlands coin, originally made of silver, with a value of a tenth of a Dutch guilder. The current 10-euro-cent coin that in circulation today in the Netherlands is also sometimes called a dubbeltje.

The name "dubbeltje" is the diminutive form of the Dutch word "dubbel" (Dutch for "Multiplication") because it was worth two . When the decimal system came to the Netherlands (about 1800) the 10-cent coin was named a "dubbeltje". In Dutch slang, a dubbeltje was named a beisje, from Dutch-Yiddish beis, the value of two stuivers. Automatic translation from Dutch to English often translates "dubbeltje" as "dime".

The central opening in a Compact disc is exactly the size of a dubbeltje (15 mm). Joop Sinjou, head of Philips audio products development, said that "De snelste beslissing in de ontwikkelingsfase was over de diameter van het gat in de CD. Ik legde een dubbeltje op tafel en dat werd de maat." ("The fastest decision in the development phase was about the diameter of the hole in the CD. I put a dubbeltje on the table and that was the size.") The same form factor with the dubbeltje-sized center was carried over on newer disc formats such as DVD and Blu-ray.

There are Dutch sayings about the dubbeltje:

• Dat was een dubbeltje op zijn kant (That was a dubbeltje on its edge): A narrow escape.
• Voor een dubbeltje op de eerste rij/rang (willen) zitten (To (want to) sit on the first row/rank for a dubbeltje): He gets (or wants to get) more for his money than he would expect from the price paid.
• Wie voor een dubbeltje geboren is, wordt nooit een kwartje (He who is born for a dubbeltje will enver become a kwartje): If you're born poor, you'll never become rich.
• Zo plat als een dubbeltje (As thin as a dubbeltje): Really thin/flat.
