[QUOTE="GDJMSP, post: 26102917, member: 112"]I tried to look at the full report but the link you posted isn't working, at least not right now. [ATTACH=full]1664163[/ATTACH] But here's the problem I see with those reports. Jeff touched on it when he commented about grade and type, but he didn't really mention just how important that was. At least for the purposes being discussed in this thread as it pertains to individual coins with a given state of wear. To consider those reports you have to also consider the source of the coins the mint is testing. What I mean by that is this. When coins become so worn by wear that they are no longer readily recognizable, banks return those coins to the mint for replacement. So I have to wonder if it was only those coins that were returned that the mint conducted their studies on. If that were the case then one would have to expect the results of the study to be pretty much exactly what they are. But if the study were instead conducted on coins pulled randomly from circulation, as opposed to only those coins returned to the mint for replacement, then we would expect the results to be extremely different, and show nowhere near that amount of weight loss.[/QUOTE]
