Does it worth to restore these? If - yes, how can it be done?
Thank you for any comments or suggestions.

Deutsches Reich & 200 MARK overprinted in black with 2 Millionen & 200 Mark overprinted.

In "MNH" condition, these stamps, singly, catalogued around 50 cents apiece. In sheets they are worth somewhat more because of the selvedge inscriptions etc. If possible, can you store your sheets so that they are flat? This would help preserve them. A sheet in VF or better condition could sell for roughly $50.00 to a lot more because of the inscriptions. A German expert may be able to tell you more on these?

Thank you very much. I found more bloocks like this. All stamps are very dry... I am afraid of just pressing them as is (many will be lost).

There are paper restorers around,
check your local phonebook or online.

May be beyond the value of the stamps, but the sheets repaired would be handsome.

Definitely worth a phone call.

They look ruined to me.
