[edit] Wikipedia & me:

How I discovered Wikipedia, I do not remember. But from being a reader I slowly became a contributor. Although I don't work that much on Wikipedia I do see myself as a Wikipedian. I don't go searching on Wikipedia what I can edit next, I edit what I find and want to do. This means I add and mainly improve a lot of small things and only rarely I make large edits.

Liberty head nickel, obverse side, showing Liberty wearing a coronet and wreath

The Liberty Head nickel was an American five-cent piece. It was struck for circulation from 1883 until 1912, with at least five pieces being surreptitiously struck dated 1913. The original copper–nickel five-cent piece, the Shield nickel, had longstanding production problems, and in the early 1880s, the United States Mint was looking to replace it. Mint Chief Engraver Charles Barber was instructed to prepare designs for proposed one-, three-, and five-cent pieces, which were to bear similar designs. Only the new five-cent piece was approved, and went into production in 1883. For almost thirty years large quantities of coin of this design were produced to meet commercial demand, especially as coin-operated machines became increasingly popular. Beginning in 1911, the Mint began work to replace the Liberty head design, and a new design, which became known as the Buffalo nickel, went into production in February 1913. Although no 1913 Liberty head nickels were officially struck, five are known to exist. While it is uncertain how these pieces originated, they have come to be among the most expensive coins in the world, with one selling in 2010 for $3,737,500. (more...)

Picture of the day
Autofluorescence in tissue paper

A light microscope image of tissue paper. The tissue was illuminated with ultraviolet light making it glow blue due to natural autofluorescence, the same effect which makes paper glow with a black light. The tangled network of fibres are cellulose fibres which are derived from wood and make up all types of paper and cardboard. It is a combination of the properties of cellulose and additional optical brightening agents which makes the tissue glow.
