Once a month we all get excited about lustre. It's really the lack of standardisation that I find unhelpfull and yes, CCC do occasionally describe a penny in an unhelpfull way - I mean really, what are we supposed to make of uncirculated with full lustre, lightly toned ? (Lot 86) I wish the industry would adopt the Unc with x% lustre as a standard. We've already decided, haven't we, that BU is used far too often where pennies are concerned. To me it's very simple really, toning is oxidation, copper reacts with either one or two oxygen molecules, can't remember which is the rarer. So as far as full lustre is concerned, has oxidation commenced, yes or no. If no, then it's full lustre, if yes, then what percentage of the lustre is left. It is surely much better to describe a penny as unc with 80% remaining lustre than full lustre with 20% degredation. Now I know no-one is doing that, but you get my point. Pennies with full lustre are quite hard to find and getting harder. I get a bit depressed sometimes, it seems that a coin is described as full lustre as a standard and then blazing full lustre if it's about 85% + There is too much hype in the world. No-one is bashing the collection, it's owner or CCC, it's all good clean fun.
