@ Peter, I'm afraid qaziright's offer is the first one.

I now have 10 of the series, and I have tried to sort them out by the references quoted by the various sellers on ebay as well as the ones I've bought. The result is this list of what I know should be available (the ones I have in bold), but I'd very much appreciate any corrections, further details of varieties and mintages. I know the earlier ones were struck by Heinrich Kissing, but information as to who struck the later ones (or confirmation it was also Kissing) would be welcome.
