Editing Guilder (section)

==Gold guilder==
The guilder or gulden was the name of several gold coins used during the [[Holy Roman Empire]]. It first referred to the Italian gold [[florin]], introduced in the 13th century. It then referred to the [[Rhenish gulden]] (''florenus Rheni'') issued by several states of the Holy Roman Empire from the 14th century. The Rhenish gulden was issued by Trier, Cologne and Mainz in the 14th and 15th centuries. [[Basel]] minted its own ''Apfelgulden'' between 1429 and 1509. [[Bern]] and [[Solothurn]] followed in the 1480s, [[Fribourg]] in 1509 and [[Zürich]] in 1510, and other towns in the 17th century.

The ''[[Reichsmünzordnung]]'' or imperial minting ordinance of the [[Holy Roman Empire]] first defined standards for the [[Rhenish gulden]] (''Rheinischer Gulden'') in 1524. It also defined a silver ''[[Guldengroschen]]'' of equal value to the ''gulden''.{{r|Shaw_1896}}{{rp|page = 363-367}}{{rp|page = 364-365}}

The standards of the [[Rhenish gulden]] has changed over the centuries, as follows:{{r|Munro}}{{rp|page=19|quote=Rhenish florin }}{{r|Shaw_1896}}{{rp|page = 364-365}}
* In 1354, it was minted {{frac|66}}th a [[Cologne Mark]] of gold, 23{{frac|4}} karats fine; hence {{convert|3.43|g|ozt|abbr=off}} fine gold, or identical to the Florentine [[florin]].
* By 1419, it was minted {{frac|67}}th to a Mark, 19 karats fine; hence {{convert|2.76|g|ozt|abbr=off}} fine gold.
* By the 1559 ''[[Reichsmünzordnung]]'', it was minted {{frac|72}}nd to a Mark, 18{{frac|2}} karats; hence {{convert|2.50|g|ozt|abbr=off}} fine gold.
