100 to 500. Maybe more if it left the factory that way.
General George S. Patton wore a set of matching pearl handled pistols. The above answer, and the question which preceded it, are based on misconceptions of the American press during World War 2. Patton had two Colt .45 pistols with ivory handles instead of mother-of-pearl, but he only wore one at a time, not both. Under his uniform tunic he carried a .32 pistol as a backup.
There are numerous types of pearl-handled pistols available from various firearms manufacturers. The specific number of different kinds can vary based on factors such as design, brand, and customization options.
You need to get it lettered by S&W to see if it left the factory in that configuration. If not factory, value is about 200-300 USD. If factory, seek an appraisal.
Depends on overall condition, if it left the factory that way, whether you are selling, buying, insuring, caliber, barrel length, box,etc.. Price range 75-500

100-300 USD
I suspect it is nickel or chrome plated since S&W never made a stainless revolver in that caliber. Would need to know all of the markings on your gun to answer the question.
