Message:: [QUOTE="kanga, post: 793709, member: 9270"]We're running into a lot of semantic and terminology problems here.That's why a topic such as this benefits from face-to-face discussions where a working definition can be established.I used the term luster/red to cover all coins, "red" referring to copper coins and luster referring to silver (and gold and nickel).I guess a better term would be "new Mint surfaces". I know that BN copper can have a fair amount of Red, but not enough to earn even the label RB (nevermind Red).And sticking just to copper for the moment, here's what I'm trying to find out.For AU coins, does toning affect the grade?Everything else being equal (wear, marks, etc.) would a BN coin receive a lower grade than an RB which would receive a lower grade than a Red coin?[/QUOTE]
