Steiff Bear

 I received this Steiff Bear from my grandmother when she passed away.  It is about 17 inches tall with brown fur on the body except for the face, feet, and palms of its hands these are colored light brown.  It has a red collar with silver spikes around it with a one gold bell.  It has a yellow tag on it's left ear that says Steiff KNOPF IM OHR it also says 0175/42 on the back of the tag it says all new material, PA55 MA55 73 (not sure if it is actually a 5 or an S) Covering 50% wool 50% Cotton, Made in west Germany.  It also has darker coloring on top of its nose and small marks near it's eye's.  My grandmother used to collect bears I believe she bought this in the 70's (not sure though) I always just remember seeing it in her house.  I was just curious as to what this is worth or an estimate and any other information you know about it.

Thank you!
