Yea i'm alittle confused too, thats why i made this post ;p
I got 20 eagles, 121 40% half dollars and 55 60% half dollars
How do i compute?
Goddamn. You're going to make me work! Save these formulas for your future reference. All you need are these and the spot price and you can calculate value.
Kennedy Halves = $2.58 * 121ct = $312.18
SAE = spot + $2 = $19.11 x 20 = $382.20
60% Halves.... I'm guessing you mean 90% because I've never heard of 60%s
$6.20ea * 55 = $341.00
Current worth I'd value at $1035.38 melt. Looks like you did well!

Using the latest metal prices and the specifications above, these are the numbers required to calculate melt value:
$17.11 = silver price / ounce on Feb 08, 2008.
.40 = silver %
$3.4907 = copper price / pound on Feb 08, 2008.
.60 = copper %
11.5 = total weight in grams
.0321507466 = ounce/gram conversion factor
.00220462262 = pound/gram conversion factor (see note directly below)
The NYMEX 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 40% silver value :
(17.11 × .0321507466 × 11.5 × .40) = $2.5304566618
$2.5304 is the rounded silver value for the 1965-1970 silver Kennedy half dollar on February 08, 2008. 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 60% copper value :
(3.4907 × .00220462262 × 11.5 × .60) = $0.0530995
3. Add the two together :
$2.5304566618 + $0.0530995 = $2.5835561618
$2.5835561618 is the total melt value for the 1965-1970 silver Kennedy half dollar on February 08, 2008.

1. Calculate 90% silver value :
(17.11 × .0321507466 × 12.5 × .90) = $6.1886168361
$6.1886 is the rounded silver value for the 1916-1947 silver Walking Liberty half dollar on February 08, 2008. 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 :
(3.4907 × .00220462262 × 12.5 × .10) = $0.0096193
3. Add the two together :
$6.1886168361 + $0.0096193 = $6.1982361361
$6.1982361361 is the total melt value for the 1916-1947 silver Walking Liberty half dollar on February 08, 2008.
