First comes the number of the coin in the sale, number you will use to reference the coin on your bid sheet. Each coin is named, with, between brackets, the alloy or metal, the diameter of the coin (on the 12 hours axis), the die axis (usually 6 o'clock, coin type strike, or 12 o'clock, medal type strike, - of course, for hammer strikes, all other possibilities exist, no rules being settled for the die axis). Following information between brackets is the weight. Then comes, if known, the official weight and the official fineness of the alloy.Following this, comes, when applicable, for the particular alloy , the quantity of coins struck per marc of bullion (marc was a weight measure during the middle ages, which might change from place to place) - for instance one marc from the city of Troyes was 244.7529 grams of bullion which produced 30 gold louis aux lunettes, which is, per coin, 8,158 g. Then, if appropriate, comes the value of the coin in account unit, usually the tournois or parisis currency. Then, if needed, the fineness in carats or deniers and grains. In France, mints valued fineness in "l'argent le roi", good for 11/12th of fine silver. Then comes the complete description of the obverse type and... A/ Obverse R/ Reverse type. After these descriptions, as accurate as possible, comes, if known, the name of the Mint Master, the name of the engraver, the name of the General Mint Master and of the General Mint Engraver.Then afterwards,come as many bibliographical indications as needed to reference the coin, the rarity level, the grade of wear, the starting price and the estimated market price. After these, we usually give an historical notice about the coin or the period when it was issued and, if necessary, the translation of the legends of the coin.
