2004 20p striking problems?

Is it just me or is this coin suffering from striking flaws or something, i've seen alot of 2004 20ps exhibiting this, indeed it's hard to find one without, this is an average one, i've seen better and i've seen alot worse. Kinda looks like the field was a sand pit and the effigy of Her Majesty came crashing down...

    Haven't seen any of these in hand yet, but there's something odd there.

    Looks like some die pesting (sic?). If I am right that usually happens when the presses do not exert enough pressure.

    I was thinking something along pressure lines myself, but i'm suirprised you say not enough pressure, i was wondering if it was too much pressure. But i'm not all that gemmed up on the enitre process of actually minting the things, so i'm open to all suggestions here.

    Just compared it with a 2003 strike and the 2003 issue does not exhibit this sandpit phenomenon, and the strike is much much better. Lack of pressure certainly would seem a likely cause.

    I'm waiting to see what Cladking says on this one, if anyone knows about stuff like this, he's the man.


    I can send you one over with that payment i'm shipping over Wybrit should you wish?

    I'm not really confident speculating on this since I've not seen anything quite
    like it and the picture is a little difficult to make out but my first impression was
    die fatigue. This of course assumes that this pattern isn't the same from one
    coin to another.

    It's possible the concavity of the coin was switched to bring up the reverse and
    the added stress caused unforeseen stress on the fields of the obverse die.

    This phenomenon is on quite a few 2004 20ps that i've seen, i haven't seen one without it yet.

    The reverse has it too, at either side of the rose leaves. I think it often occurs there though, i've got a 1993 and it has very very faint lines like this just next to the left hand side rose leaf... no where else.

    A 2003 specimen has the same problem on the reverse but only located to from the right hand side of the 3 in the date to the inner edge... no where else.

    It might be too much pressure too, I do not know. I have the one coin that exhibits similar lines radiating outwards from the center, the Vietnam 1946 1 dong issue, and my local dealer suggested that not enough pressure caused the pressure lines.

    She looks lonely. Maybe she should come across the pond to visit the other 20p here in my collection.

    What do the 20ps in the 2004 BU sets look like?

    I looked at a BU set ages ago but i didn't take note on how the 20p looked though.

    Wonder if they're using left over 2003 obverse dies?

    I'll send you one over Kuhli with the other stuff that i'm gonna send over, when i know what that stuff is of course.
