Dubbeltje
A ''dubbeltje'' () is a small former Dutch coin, originally made of silver, with a value of a tenth of a Dutch guilder. The 10-euro-cent coin is currently also called a dubbeltje in the Netherlands. The name "dubbeltje" is the diminutive form of the Dutch word "dubbel" (Dutch for "double") because it was worth two stuivers. 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. The central opening in a CD is exactly the size of a dubbeltje. 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.") There are Dutch sayings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stuiver
The stuiver was a coin used in the Netherlands, worth of a guilder (16 ''penning'' or 8 '' duit'', later 5 cents). It was also minted on the Lower Rhine region and the Dutch colonies. The word can still refer to the 5 euro cent coin, which has almost exactly the same diameter and colour despite being over twice the value of the older coin. Netherlands The ''Stüber'' emerged from the ''vierlander'' ("coin of four provinces"), that Philip III of Burgundy had minted from 1434 as a common denomination for Brabant, Flanders, Holland and the Hainault (''Hennegau'') and which had a value of Rhenish ''gulden''. It corresponded to 3 Brabant ''Plakken'', 2 Flemish '' Groten'', 16 Dutch ''pfennigs'' or 1 Artesian ''schilling''. The name "stuiver" derives from the Dutch ''stuiven'' ("flying sparks"), since on early Flemish ''stuivers'' "spark-producing flints of the Collar of the Golden Fleece" were depicted.

Diameter
In geometry, a diameter of a circle is any straight line segment that passes through the centre of the circle and whose endpoints lie on the circle. It can also be defined as the longest Chord (geometry), chord of the circle. Both definitions are also valid for the diameter of a sphere. In more modern usage, the length d of a diameter is also called the diameter. In this sense one speaks of diameter rather than diameter (which refers to the line segment itself), because all diameters of a circle or sphere have the same length, this being twice the radius r. :d = 2r \qquad\text\qquad r = \frac. The word "diameter" is derived from (), "diameter of a circle", from (), "across, through" and (), "measure". It is often abbreviated \text, \text, d, or \varnothing. Constructions With straightedge and compass, a diameter of a given circle can be constructed as the perpendicular bisector of an arbitrary chord. Drawing two diameters in this way can be used to locate the center of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Reeding
Reeding or milling is a technique wherein a number of narrow ridges called "reeds" are carved or milled into a surface with a Castaing machine. Numismatics In numismatics, reeded edges are often referred to as "ridged" or "grooved" (American usage), or "milled" (British usage). Some coins, such as United States quarters and dimes, 1 euro, Australian 5, 10, 20 cents, 1 and 2 dollars, as well many other current coins, have reeded edges. One reason for having reeded edges was to prevent counterfeiting. Some gold and silver coins were reeded to discourage clipping, i.e. scraping off the precious metals from the edge of the coin, to maintain its stated value in precious metal. This practice was made more difficult through the implementation of reeding by Isaac Newton in 1698, during his time as warden of the Royal Mint. Another benefit of certain coins having reeded edges is that it helps the visually impaired identify different coin denominations by sense of touch alone. ...
