If users misrepresent their coins for swap, that's also a user problem, not a catalog problem. Limiting options for those that would correctly use the more complete options will not resolve mis-use, but WILL increase accuracy overall, as those that DO use the catalog properly (to the best of their ability) continue to do so, with the more complete and accurate options available Users mis-using the catalog is a user problem, not a catalog problem. So don't try to make any kind of statistics per year and variety. So we end up with a very precise CATALOG, but with no guaranty of the proper use. You have no idea how the distribution of the varieties are, when they are not correctly entered by our members. A type collector will just put his coin, be it for his collection or for swap, in any year line! I've had multiple swaps, where the variety (second, third or whatever year line) is not respected. I actually collect by year and variety! The problem is more for the swaps and statistics. I think the catalog is more accurate, if it includes all varieties as year lines.
