Dan,
Do you know the expression: "Having a face only a mother could love"?......
I don't presume to know your situation, but if I was starting to collect Germany inexpensively, I would buy some German kiloware (or worldwide kiloware heavily populated with German stamps) expecting to swap out most of the "tattered" stamps above.
Also surfing the net on one's favorite "Bay" might yield some beginner Germany collections at minimum expense and allow you to swap out the ripped, bruised and wrinkled (at 68, I winced at that phrase

).
Best wishes and good luck,
Greg
