Thought was a mini ball

[Tenn treasure hunter]

At my fathers house found about 20 of these when digging a line for a pipe. Brought my metal detector and pinpointer to find more and it doesn't set off a signal on the pinpointer or the ace 250 any ideas what it could be? Thanks for the help.

You mean musket ball, the minie ball is conical shaped tip a musket ball is round, what are the measurements.

 

[Tenn treasure hunter]

I don't think it's a musket ball it's not uniform all the way around. It's about an inch inch and a half

If the diameter is 1.5 " it is not a mini ball or musket ball it is too large of a caliber. It would be more like grape shot.

I've never seen grape shot made of lead like that though,aren't they usually iron? It seems like if it were lead or iron it would make your detector and pin pointer go off.

 

[Tenn treasure hunter]

Yes that's my thought if it was metal the detector would have went off.

Well I should have read your post instead of running with the title, not magnetic that changes everything. What gullum wrote, lol.

Are they stone?

 

[Tenn treasure hunter]

I don't think so. I really don't know.

Looks like larger than normal clay marbles

I'm thinking on taking a hammer to it see if it breaks

If you want to preserve it test it for hardness, here's a link that explains it:

Thanks for the link Ant, good info.

 

[Tenn treasure hunter]

Yes great info! However, nothing on the list scratched it, and I do not have a diamond to try man this is really bugging me

Thank all of you for your help so far. Let's keep the ideas flowing.

Could be ceramic media, used for polishing or grinding.
