Which major meteorite family represents the rarest class, comprising only about 1% of finds?

Stony-Iron meteorites

Meteorites are broadly categorized based on their primary composition into three major families, each having a distinctly different abundance among recovered falls. Stony meteorites are by far the most common, accounting for approximately 94% of finds. Iron meteorites make up the next largest group, representing roughly 5% of finds. The rarest class is the stony-iron meteorites, which collectively account for only about 1% of recoveries. These fascinating objects are rare because they represent a mixture of both the metallic core material (iron-nickel alloy) and the silicate mantle material of their parent bodies, indicating they originated from the transitional boundary zone between the core and the mantle of an ancient, differentiated planetesimal.
