These are 7 coins of the Deutsches Reich, from 1928 to 1937, which includes the Weimar era. As far as I know, even the smaller denominations had silver content. There are: 5 Mark Hindenburg1936 and 1937, I can't determine a mint sign, probably on the edge?
The 1 Mark pieces are 1936 D and 1937 A, the 50 Pfennig are 1928 A, 1935 E, 1936 A.
