Yes, and on the lids. The used lids are usually marked with the previous contents.
I remove the magic marker markings with lacquer thinner, then just strike a black mark across the lid, thus identifying as a used lid.
Most lids that have been used, you can readily tell. Some not so much, like a lid that has been used for vacuum sealing.
I try and use used lids to put on clean jars for storage. I can't always, so then I put new lids on. And I leave the band a little loose.
And band pressure. I've had new jars come in that the band was way to tight, and had the seal on the lid compressed. So I always ck new jars when I get them.
