enworb Pillar of the Community Australia 4411 Posts	Posted 12/26/2011 08:01 am I bought this coin graded at EF which I think is about right based on wear? I was wondering if people think, what I will call carbon streaking (dont know if this is correct?) which can be seen on the reverse, detracts from the grade much. There is quite a bit of lustre in an around the lettering on both sides but I wasnt able to photograph it too well. Also couldnt get the lighting right for the 7th & 8th pearls but they are there much stronger than the photo shows. Thanks Report this Post to the Staff

It depends on the dealer whether carbon will affect the coins grade, I know some put more relevance on it and some not. Personally I like a very streaky coin but send it to PCGS and they hate it. They will definately downgrade it due to the streaking. Report this Post to the Staff

Very rare you will get the same streaking on different coins. A bit like a coins fingerprint Report this Post to the Staff
sel_69l Bedrock of the Community Australia 21788 Posts	Posted 12/26/2011 10:19 pm In most cases, 'carbon' streaking or spots are not carbon, but are patches of metallic sulphides. I have a silver rupee of Edward V11 uncirculated, with impossible to remove black spotting on it. If those spots were pure carbon, they could be easily removed without damage to the coin. They have permanently etched their way into the surface of the coin, reducing the value of the coin down to bullion value. I know of no way of effectively removing them. This particular coin is in my hoard of junk silver. No loss to me, I bought it at below melt anyway. Report this Post to the Staff

sel_69l Bedrock of the Community Australia 21788 Posts	Posted 12/27/2011 05:29 am enworb is right. The totally dominating black marks on my rupee ruin it. It must be remembered that 'patination', which can actually enhance eye appeal, can help to show a coin off. It also must be remembered that patination is really a form of mild surface corrosion. Beauty can be a delicate thing. Report this Post to the Staff
