Possible Penny Indent

[enworb]

Im not too sure about this one. Its quite different to the indent I purchased a little while back. There is some weakness in some of the devices around the 'indented' area.

Struck on a thinned planchet.  Very similar to this one:

Thank you mark. Any idea how a thinned planchet like that can occur?

No idea.  Perhaps when the metal was rolled there was some scrap on top of the metal that was rolled into the strip.  After rolling it fell out and left a "dent" for want of a better word?  Another idea is that the planchet was punched out of the metal strip near the edge and perhaps it was thinning out near that edge.  I actually don't really know.  The one we've got was the first one I've seen, and it's funny that now I've seen another one just a couple of weeks later.

I'll buy it if you want to sell it.  PM me and I'll tell you what I paid for mine.

Interesting that both are 1964's and both in really great condition.

Geez I'm going to have to dig my 64's out now .... (surely I would have seen it if I had one, but no harm in checking .... lol)

A cold shut could do that if the metal separated before being struck.

And speaking of cold shuts, I just found a 2012 10¢ a few minutes ago with a lovely example on the reverse. Looks like a miniature crochet hook squashed into the coin. Piccies in due course...

Ive never heard of a cold shut fulvio. Care to elaborate for me?

[Fulvio]

Sure. Cold shuts happen, usually in casting, when hot metal meets cold(er) metal. It crystallizes into two separate but attached chunks. In the case of coins, they show us as spurs from the rim extending into the coin in a curve. Sort of like a little scythe shape.

I can see a big cold shut falling apart, depending on how the planchet is cut into it. That would give you the right shape to end up looking like those pennies.

Thanks fulvio that sounds half plausible

the value is held with the collector
they usually determine the value by what they'll pay
or swap

[Fulvio]

Indeed, RG. "Its worth whatever some mug will pay for it"

[robbiegal]

yes
there has been many a time I have made a mug of myself with coins
I am a little wiser now

A cold shunt was described to me this way.

Sometimes you may have seen your mum or someone rolling pastry with a rolling pin.   Some times the, a scrap piece of pastry was folded onto the rolled pastry and was then itself, rolled.   Now, at a a glance, this tag appeared to have been absorbed into the rolled pastry.   But wait.   Leave the pastry alone for a while and this tag will start to lift slightly.   it has not fully been absorbed into the bulk pastry .   This is the same in the steel metal industry.   I used to work at ALCAN Australian and watch the large aluminium ingots being rolled into long sheets, up to 3 miles long.   On occasions, I would witness a loose bit of aluminium on the sheet before it went through the mill.   Same as the pastry example.

Now when that piece of sheet/blank is stamped or put under some form of mould pressure, it will lift up.   Just as shown in the scans.

That is a cold shunt.
