You quite often get a "Wood Grain" effect on Aussie coppers. We tend to call it carbon streaking    |

Is there a theory on how this carbon streaking happens?
I have read that the woodgrain effect is do to couple reasons: because of grease on the die; because the copper was not mixed properly as an alloy. Not sure if either is correct.

That's a good question. I would imagine its due to impurities in the planchet metal.

I like a bit of carbon streaking. It is however poorly mixed planchet metal and is detracting to a "perfect coin". These coins therefore are not graded as highly by PCGS. The imperfection goes far enough to become a flaw on this coin to the left of the P of penny.  |

TPP you just know I don't give a hoot about PCGS. To me that is a beautiful example of a 1926 penny. All the graded Pennies are characterless and have no soul. This one is gorgeous, I love it  . By the way whats with the rim from 10 o'clock to 3 o'clock? |

It's a ramstrike error. I'm in love with it not only for it's woody look but because early errors are difficult indeed. You know Trout I love my coins in PCGS slabs, I even put them in there on purpose.

I will disagree with "characterless and have no soul", PCGS MS64RB.  |

Ive before over that coin and I'm doing it again! I have heard PCGS are looking much more favourably at colour now and its possible to have some beautiful coins like this one in slabs. Being in the slab may even prevent them from losing the beautiful colour to further unsightly toning which can only be a positive. The other benefit I see is it may make a novice collector think twice before rubbing like heck to get rid of the black streaks which actually add to the coins beauty IMO. I know if I owned a GEM Aussie predecimal I wouldnt be getting it out of its 2x2 and fumbling with it. Id be leaving it in the holder and looking at it. Lower grades is a different story as theres no harm in holding them. I'm starting to see little difference between very high grade coins being in a 2x2 compared to a slab. |

I am starting to love slab coins, it is just as beautiful as normal one in high grade, it is also a great way to protect your loved coins. I am thinking of slabbing all of my high grade coins, prefer PCGS system
