Re: Whats a cent stock 10c weigh?
- Hey, everyone. We're able to do full archive searches again.
Yipee! Type in "cent stock". Make sure you use quotes. That way
the two words are associated with each other. The weight that Mike
Byers cited is 2.9 grams, which is WAY more than a cut-down cent
planchet should weigh. A cut-down cent planchet should weigh less
than 2.5 grams.
With this heavy weight, the smaller-than-dime size planchet would
have to have been much thicker than either a cent or a dime. Either
that, or the core is not zinc, but a higher density metal. I wonder
if anyone has done a specific gravity test.

- What exactly happens when you attempt to do a search? Is anyone else
facing the same difficulties? Maybe like access to full size images,
Yahoo restricts full search privileges to the owner and moderators.
If so, that's very unfortunate.
I strongly doubt that the outer margin of these coins was sheared off
by the collar during the strike. It is almost impossible for an
oversized planchet to pass through the feeding mechanism. Only a few
strikes on oversized planchets are known among U.S. coins.
Each one of these "cent stock dimes" is perfectly centered. To have
each of these "sheared broadstrikes" perfectly centered is not at all
likely. To have them all sheared (rather than broadstruck) is
equally unlikely. The closest error to these would be an elliptical
strike clip, and none have been reported since 1994. None at all are
known among dimes (although I strongly suspect some exist).
The reported weakness or absence of reeding along parts of the edge
is not what you'd expect of this kind of "circular strike clip".
Also, you'd expect to see microscopic stress splits (from stretching)
in the copper plating along the periphery of the reverse. This has
not been reported.
You'd also expect to see a weakly-struck, rounded shoulder on the
reverse face. This too is not in evidence.

- Hi Guys. Continuing with this thought I've been reading upon coming
home from work.Is it possible that these copper dimes are dime stock
maybe close to the end of the sheet where the thickness of the now
copper core stock is rolled for an inch or two to dime thickness
before the sheet ends? The clad might have ended 2 inches before? A
planchet or 2 might have been punched out of this now clad-less end of
sheet stock with the correct (or close to) thickness. I see this in
other denominations where clad turns to copper at the end of the
sheet. Just a thought....Marc
- I don't see how these could be dime stock when you've got copper
plating (or copper cladding) over a zinc or zinc-colored core. You
seem to be describing a pure copper dime. But in these coins, the zinc
core is visible on the edge.

- Just for the record, a dime struck on a cent planchet cut down to the
size of a dime planchet should weigh around 2.21 grams. At 2.9 grams
these "dimes struck on cent stock" are way too heavy.
