Could be a large mill ball brought from the ball mills used for grinding
ore in the western US. I have seen them up to 6 inches. Would have some
nickel in it as a mill ball. Very tough to cut as well as I have cut
and polished a mill ball, will wear out the equipment fast.

I would like to show a picture of what a friend of a friend thinks might be a
meteorite but I know we are not permitted attachments in our emails to the

The object which this person dug up (on a 20 acre rural plot in Illinois) is
very round, 9 1/4 inch in diameter and weighs 110 lbs. That's pretty much the
density of iron, 7.87 g/cc or 492 lb/ft3. It's surface is rusted, but it is
nearly perfectly round. The rusted surface gives the impression of thumbprints
but it is simply rusted. I think it's a cannonball but am not certain that old
cannonballs were this size and weighed 110 lbs.
I filed off a chink to do a nickel test but so far haven't the right chemicals to do one.
Any ideas?
Dave
