Bonsoir
Compte tenu de l'état de ta pièce, elle vaut son poids en argent et cuivre métal :
voici un calcul fait sur un site américain avec les valeurs du jour ( désolé c'est en anglais et en dollars )
Using the latest metal prices and the specifications above, these are the numbers required to calculate melt value:
$31.15 = silver price / ounce on Jan 25, 2013.
.90 = silver %
$3.6363 = copper price / pound on Jan 25, 2013.
.10 = copper %
26.73 = total weight in grams
.0321507466 = ounce/gram conversion factor
.00220462262 = pound/gram conversion factor (see note directly below)
The CME uses pounds to price copper and that means we need to multiply the metal price by .00220462262 to make the conversion to grams. The silver price is based in troy ounces and that means we need to multiply the metal price by .0321507466 to make the conversion to grams.
1. Calculate 90% silver value :
(31.15 × .0321507466 × 26.73 × .90) = $24.0929818087
$24.0929 is the rounded silver value for the 1921-1935 silver Peace dollar on January 25, 2013. This is usually the value used by coin dealers when selling these coins at melt value. However, the total melt value is continued below.
2. Calculate 10% copper value :
(3.6363 × .00220462262 × 26.73 × .10) = $0.0214282
3. Add the two together :
$24.0929818087 + $0.0214282 = $24.1144100087
$24.1144100087 is the total melt value for the 1921-1935 silver Peace dollar on January 25, 2013.
Donc
24 Dollars
