Some of the reference catalogs are grouped. One major grouping is the Krause catalogs where the codes are combined under KM (mostly).
But there are also groupings of catalogs with separate codes. One in particular is Die Münzprägungen der deutschen Staaten by Kurt Jaeger. At the bottom of the combined page is some of the items referenced, and it includes items from several of the volumes.
There is also a link to “See the 171 coins”. But there are two problems:
- Instead of a link to all 171 it only shows the items for Band 1 (Wuerttemberg) – there is no way to see all 171.
- In addition to a corrected “all coins” link there should be 12 (currently) links for the twelve individual volumes. This would be useful for the people who have one or two but not all twelve of the volumes (which I suspect is most people).
