How are stony-iron meteorites formed?

During the period of planet formation, mesosiderites originated by the low-velocity collisions of large metallic core fragments with the surface of a differentiated asteroid-size body . these collisions reduced mantles and crusts to small silicate fragments but left cores in the form of large, durable metal fragments.

How much is a stony iron meteorite worth?

Common iron meteorite prices are generally in the range of US$0.50 to US$5.00 per gram. Stone meteorites are much scarcer and priced in the US$2.00 to US$20.00 per gram range for the more common material. It is not unusual for the truly scarce material to exceed US$1,000 per gram.
