High grade NGC copper crossover attempts

toothpuller

Hi David,

Everybody seems to be complaining that their NGC copper will not cross. Does this have anything to do with your copper guarantee? Would you have any idea on the percentage of successful high grade copper crosses? I am assuming it is lower than the overall crossing rate.

Thanks

I am not sure what the NGC copper crossover rate is and I have no way of finding out. I have not noticed a difference in their copper grading compared to their other grading. I don't think their guarantee on copper, or to be precise their non-guarantee, effects their grading of copper...but it may effect the market value of their copper. I believe they grade copper to about the same standards as they grde other series.
