Dave, hallmarks are serious thing for every country no matter what the time period is.. They were like an approval stamp,a stamp to guarantee the precious metal in it is at least that of the stamp.. As far as the marks on the link. They are not even German marks.. Check any of the silver forums. , and even the 1800's German law document that was posted earlier. quarter moon, and crown.. Well there are different types of crown, circlets, coronet. Imperial state etc. The crown on the link is almost a dead ringer of the Swiss and Finnish crown markings [circlet],,it clearly is not what it should be - http://en.wikipedia.org/wiki/German_State_Crown
FPs comments on the content stamp is also dead on. There was never separate numbers for the content stamp. If 800 it got stamped once, 800,,not 3 times 8-0-0 that is ridiculous.. Again this is a dagger site. The dagger some seem to like. But go to any silver site and they will confirm 100% about the content die stamp and the markings for Germany..
So the links we know aren't period. The dagger itself,,well that's up to you experts. .
