How much is my old telephone worth?

Question

telephone has hand crank

Answer 1

You need to provide more information, maybe a picture.

Answer 2

There are many variations of crank telephones.  If you describe the size and shape of the phone (square, rectangular, straight top or cathedral top), what it is made of (wood, metal or bakelite) and look for a manufacturers name,  I can assist you.  The manufacturers name can typically be found (but not always) on the front or back of the transmitter (where you would speak into), the receiver (where you would listen), a tag on the front or top, inside the box on the crank generator or magneto or sometimes there is a paper schematic that contains the name and model number.
