Some old German stamps

Here are some old German stamps that might be interesting to you.
Does someone maybe know how much they could be worth?

 

Left plate:
second row,second stamp (25 Pfg.) from the left is around $ 30.- cat.value.But the cancellation is smeared and the whole appearance of the stamps looks dirty.So it is no more worth than maybe $ 1.-.
Same row,fourth stamp(5 Pfg.),is about $ 10.- cat.value.But again: it is in such a poor state,that it is worth nearly next to nothing.
Third row,second stamp (40 Pfg.): cat.value ca.$ 20.-.The cancel is not readable,so the net value
will be $ 5.- or a little less.
Third row,fifth stamp: cat.val. $ 8.-,showing parts
of a wave-cancel (killer),so net perhaps $ 2.-.
Row eight,fifth stamp (2 Mark),if mint,n.h. cat.val.
about $ 70.-,if mint,hinged $ 25.-,if cancelled (the
scan is not clear) about $ 3.-.For both mint about
20-30% cat. is realistic.If it should be used,it is
nearly worthless,because the cancel is there in traces only,if the stamp is cancelled at all.
All other stamps of that plate are of little value,no
exceeding $ 1.-,but a number,due to poor state,
are worthless.
Right plate:
Quite a nice group of se-tenants.It needs some time
to check all one by one.So it would be advisable
to get a catalogue,what lists se-tenants.(Michel)
The best ones I found on a first glance are
the 7 1/2 + 15 Pfg. with a cat.value of about $ 130.-.if mint,never hinged.

 

Thanks so much, Werner. I will let my husband know to get a catalogue.
