I experimented with a batch of meatballs and a batch of diced chicken breasts the other day. I put up 18 wide mouth pints with used lids. Of the 18 pints there was one that did not seal. This provided us with dinner that night and 17 jars for future dinners. Not a bad average if I do say so.
Everyone has to make their own decision about reusing lids or not when canning.
