Found them at a thrift store. No seams, just concentric rings on the bottom and top of the lids. There is wear on the rims of the lids, evidence of years of use. It is not case wear because the rims don't touch the bottles are fatter than the lids.

I know they are not worth much, just want to know how old they are.

Does anybody know what manufacturing process leaves these concentric rings? I know what a pontil looks like and I know what a seam looks like, I cantell you what blown in a mold is but I have no clue what makes these rings and why there are no seams.

I BELIVE IT IS WHERE THE AIR EXCAPES THE MOLD, you FIND THEM ON A LOT OF OLD MILK BOTTLES.
