weights and dimensions of popular 1 Troy oz silver dollar coins ?

Does anyone have a chart of the specifications for the 1 Troy ounce
silver coins such as the silver Eagle, Maple Leaf, Kookaburra, Panda,
and Philly?

I would like to know the nominal gross weight & fine weight, diameter,
and thickness of these coins.

Anyone have a link to a wiki or faq with reliable data?

I've given myself a headache trying to glean this off of Google
searches.

Thanks in advance!

Silver Eagle is 40.6mm diameter; 0.9993 fine silver, 0.0007 copper
(net wt. 1 troy ounce, weight 31.101 grams. Thickness? Don't know.

Esentially, all the pure silver coins should weight 31.1 grams.

Well, actually, other than that US Mint website I haven't found any.

Consider that link you offered.

It shows a gross weight of 1 Troy ounce = 31.103 grams.
Silver content is 99.9% for a silver content (fine weight) = 31.072
grams.
Diameter 40.60mm and thickness 2.98
So, those are specs from usmint.gov

Compare to a Kukaburra, the specs are identical except thickness is
given as 4mm,
(on wikipedia and a few coin dealer sites, Perth Mint doesn't have a
website with FAQs, not that I could find, anyway)
That spec gives same weight, same diameter, same fine, as an Eagle,
why is it 27% thicker?

Actual measure of a known true Kook shows nominal dimensions same as
the Eagle.

So. . . _that_ is why I'm asking: Does anyone know a source for
actual Mint specs for these items?

What brand of Google were you using?

step 1) start Google
step 2) enter "perth mint"
step 3) go to first hit: http://www.perthmint.com.au/
step 4) find silver Koala (or any other silver $1)

voila!

Technical Specifications



Silver Content (Troy oz) 1
Monetary Denomination (TVD) 1
Fineness (% purity) 99.9
Minimum Gross Weight (g) 31.135
Maximum Diameter (mm) 40.60
Maximum Thickness (mm) 4.00
Coin Designer Darryl Bellotti




That spec gives same weight, same diameter, same fine, as an Eagle,
why is it 27% thicker?

Thickness varies across the coin according to design. Dimension given can be
max, or it may be average. What is the exact diameter of your forearm? (one
figure only, please.)

Above cut'n'paste are actual mint specs.

Even if it's a maximum thickness, the dies for the Kookaburra would
only need to be "dished" a tiny bit more than the American coin for
the Kookaburra to be a mm thicker at the rim.

Another possibility (I guess)--if the finished coins are, in fact,
exactly the same dimensions, I wonder if the US planchets are 2.98 mm,
and the striking brings the rim up to 4 mm.

Well, thanks for that.

I must be using the wrong brand of Google, because I got as far as :
http://www.perthmint.com.au/catalogu...ver-coins.aspx
and could NOT find a common kook, nor any technical specifications.

I'm having similar difficulties with RCM, finding every conceivable
variant of the Silver Maple, but nothing on the common issue, and no
technical specifications.

Thickness (max.) would be rim thickness, correct?
(For a coin to lay flat, it's face must not project beyond the rim.)

If I may test your measure as a pédant, perhaps you would be so kind
as to instruct me on the technical specs of the Panda?

The Kookaburra, from McDonald's 14th ed.: 99.9%, 31.5g, 40.6mm

Thickness (max.) would be rim thickness, correct?

I'd go along with that.

Well, strictly speaking, I'm not a pedant. A pedant is someone who... (oh
never mind)

The Panda:
Name: Silver Panda
Metal: Silver 999/1000 (other sources say 99.99%)
Diameter: 40.6 millimeter
Weight: 31.1 gram (Fine Ag... total = 31.22g)
Origin: China
Face value: 10 Yuan

(from various dealers' pages)

No thickness(es) quoted.
