Why don't you look at their datasheets??
Germanium diodes are more than 45 years old. They have not been made for many years but some stores hoarded them.
A 1N34A was a common germanium diode in North America.

Is the 1N60 diode old enough as others??
Why they are not made today?
I remember one day I use them In radios and of course in crystal radios. What is the new replacement for them?
Germanium diodes and transistors leaked a fairly high current. Silicon ones do not.
they were used as the detector in AM radios but modern high gain circuits do not need them.
If it is intended for use in Crystal Radios, you still need'em to detect weaker radio signals. I use OA79 and it's been in market for around 45yrs. I still get many in local electronics shops. Their price going forward high in recent years and probably no more availability in future. So collect them
