what's this??

[trout]

I found this today, the mark is raised.
is it a die crack or a slight planchet flaw?
I am leaning towards the latter :ok:

a slight planchet flaw

Yep, that's it! :whistle2:

[Fulvio]

These planchet flaws seem to show up first as discoloured stripes, then the stripes sort of bubble up, and finally break the surface like yours. They can range from a flake or two to a split all the way across the coin. I've got many examples, mostly 20¢ & 50¢ from the eighties, which seem most susceptible.

It would be nice if the progression was consistent and predictable, so we could "farm" them, eh?

I have heeps of $1 coins showing the same sort of thing.

[Fulvio]

Goldy, you have heaps of $1 coins, period. I hear Armaguard visit you when they run short...

[Goldseeker]

Nah, not true.   Over the past couple of years my NOODLING has somewhat slowed down.

The only heaps of $1 coins I have are errors, flaking, rabbits etc.
