Orientation of places one to another, most of the time expressed in hours. In the XIXth and XXth centuries the axis was generally at 6 am, it was about a said strike " in currency ". With the Euro, we passed in a strike at 12 am, said " in medal " according to the German tradition. To obtain the axis of a coin, take it between the thumb and the index, the obverse in the face in front of you, in the place. Make the currency revolve from left to right, so as to be able to read the lapel: if the lapel is in the place, it is a strike "awards a medal"; if the lapel is back to front, it is a strike "exchanges"

Concern the place with which currencies are struck. In the time (XIXth century), places were very expensive. The incentive to use them even once broken was thus very strong in spite of the effects of "break" that it entrainait on the coin. To note that the effect "break" of the coin is so relief because the stripe is in hollow in the area

Break of coin

When has corner kick (place) is broken ("cracked"), it talk has relief mark one tea currencies which it strikes. In theory, tea worker loaded tea machine has to spot has broken to fold and destroy currencies struck with, drank very often, thesis currencies find themselves in traffic.

In the monetary domain, the measure of the purity of the gold (the "titration", the title being the proportion of fine gold contained by a currency) is made in thousandth. For example the French coins of 20 gold francs have a title of 900 thousandth (or 900/1000), what means that they contain 9 golden parts for a brass part.

The symbolized carat "ct" is a measure of purity of precious metals such as the gold. One carat represents 1/24th of the total mass of an alloy.

For example, some gold in 18 carats means that in 24 grams of alloy, we find 18 grams of pure gold. Some gold in 24 carats is some pure gold. The gold is a particularly moldable metal. It is the reason which explains that golden currencies intended for the traffic never consist of pure gold but a mixture of gold and of copper or money.

Certificate of authenticity

Certificate emitted by an institute of broadcast, allowing to guarantee the authenticity of a casket or a not circulating commemorative currency. Generally, caskets Beautiful Test contain a certificate of authenticity while caskets Glittering Universal do not contain it. We specify however this information for every casket in the column "Caskets". As for the not circulating commemorative currencies, they possess it in the majority of the cases, even if it is not systematic

According to the strike, corner kicks wear out and pass of the state "Fleur de Coin" in has more and more pronounced crushing. So, the expression "Fleur de Coin" does not indicate originally the state of (supplement) conservation of the currency drank that of the to fold. We keep the naming " FDC " for currencies because it is attested at least since the dictionary of what is Furetière ( 1690 ) to train enough all the same to deserve the respect. The state of conservation of corner kicks is nevertheless essential in the evaluation of has currency - of any period - have soon have we achieve and especially exceed the Magnificent ( SPL).

Naturally, it is on no account because FDC is registered on the box that the contained coins are actually of quality FDC
