i came across a box of smalls at an antique auction and at the bottom of the box were these 4 old stone objects. to me, they look like bullets, but i dont beleive that can be so. two of them appear to have been smashed and the other two are still in good condition. the two in tact objects prove they are not molded but more likely formed by hand, the holes in the bottom are different sizes and the lines on the sides are not exactly the same. there are two groved lines going around each one and a small hole in the bottom. does anyone have any sort of clue what they are? it has been plaguing me for a while now. thanks in advance!
