Quite a difference comparing the fixed sight ones (only stainless .32's were fixed sights) and the adjustable sight models. The adj sight models will command a higher price depending on the exact model. The fixed sight models are starting to have their prices creep up again. Condition, completeness of package plays into the cost obviously. Check the completed auctions on GunBroker as a good starting point. In the end, it's worth exactly what someone will pay for it. If you need to ask if it's worth the tagged price, it seemingly isn't worth that much to you.
I gotta add that the pair of fixed sight .32's are FUN little shooters. Got a pair of adj sight models to try now. Thinking they'll be just as fun. it is a really neat cartridge.
