Interesting. I've never seen or heard of them. However, I have a friend who has been canning for years. She does not pressure can. She does use her standard canning lids over again, and says that she can re-use her lids repeatedly, as long as the red rubber ring around the edge of the lid looks to be in good shape. She showed me a lid with a little ding on the edge of it where she'd used a can opener on it. I asked her about that. She took it, and rolled the edge of it across a wooden beam in front of her, and the ding smoothed right out so that it was no longer visible and could not be felt. Since then, I've been re-using my lids for HWB canning, but use a new lid for pressure canning.
My friend also showed me her stash of regular jars from the grocer. I asked why she was saving them. She took me to an other shelf, and showed my row upon row of produce canned in standard jars from the grocery store. All of them were using the usual lids that the canned goods were bought with. She stated that they sealed just fine, and as long as the jar sealed, it was good to go! So, I took my cue from her, and started saving all of my jars from the grocery store. Those jars seal very well, and I use them for my home made salsa, jams, apple sauce. Some of the last jars of salsa were sealed so tight that I couldn't open them. My husband had a hard time getting one open, even when he used a rubber "jar opener".
I'm not advising the reader to re-use her lids, nor am I advising the reader to re-use jars from the grocery store. Just telling you what my wise friend and I am doing.
