I have no idea what these are, but found about 15 of them.

Anyone know what these are? They feel like there is a thin rubber material on the outside and maybe slate inside? I found them in an ashy layer after some rusty material.

Throat lozenges.. just kidding, they are battery cells.. kinda toxic..

They look like game pieces...or dominoes...

 

[msleonas]

Toxic, like don't touch them?

 

[cyberdigger]

..like wash your hands afterwards, and definitely don't suck on them..

@Cyberdigger, thanks. I will definitely not do that! I will wash my hands. Should I just throw them away? How old do you think they are? This will help me decide if I should continue digging where I found them.

True, they are good for context.. I've seen them in 1950's digs and sometimes mixed with earlier stuff..
