Welcome to the forum!
It all depends on what vintage (1896 thru 1990) and what condition you want to collect! I frame Model 30s are I frames and pre model 30s are from the 1950s. Collectible condition guns with box, paperwork and tools are going to cost close to $1000. Shooting condition, no box, etc., closer to $500.
Model 30-1 made on the J frame from 1960 to 1990 are usually less and not as collectible. These .32 long small frames are more popular now than anytime in the past as more people begin to appreciate them.
Shop around and monitor the on-line auctions for sold .32s and you'll soon get a handle on condition/value, barrel lengths, grip shapes, etc.
Warning: beware, they are habit forming!
