Grandpa’s Old Rock

I’ve heard many of stories from people who want to know if the rock that one of their older relatives has treasured for years as a meteorite really is a meteorite, perhaps because the relative heard a thud on the roof and later retrieved a rock. I’ve seen a photo of only one such rock, from Ireland, that looked like in might actually be a stony meteorite. A few others have come from people who said something like, “Dad bought it from a guy in Arizona back in 1942.” Most all of the latter have been iron meteorites. Unfortunately, such rocks are of little dollar value to potential buyers if there is no paper documentation of the name of the meteorite, e.g., Canyon Diablo or Campo del Cielo.

This treasure-chest rock is not a meteorite.
