Color, texture, and flavor may go downhill, but it won't actually hurt you.
I don't think normal grocery store peanut butter jars are actually canned. Not sure about whatever gallon containers the food bank has. Under normal storage and use times, it doesn't really need to be canned because it doesn't really have any water in it so nothing can really grow in it.
Without going into a lot of detail I'll simply say that I have eaten various canned foods
years past their expiration dates... vegetables, fruits, soups, jams/jellys, cheap peanut butter that separated, dried goods, and they were all edible. Obviously I checked the seal on the items that were sealed, and checked the appearance, smell, and taste, before downing the whole container, and I was none the worse for eating them.
A friend got into a bind one time and so I decided to help him out and donated several expired cans of food to him. Most of the cans he opened were just fine, however there was one expired can of tomatoes that when he opened them there was the distinct smell of spoiled food and the water/fluid surrounding the tomatoes was saturated in tiny bubbles. I can't recall now, the can
may have had a small dent in it, but there was no obvious signs of the can being broken or unsealed...needless to say it was thrown away.
It may offend some people's sensibilities and contradict the choices people typically make regarding their subjective quality standard for food, but properly canned and undamaged food stuffs can be eaten well past their printed expiration dates. It wouldn't surprise me however, to learn that there is a true finite date in which these items truly go bad, but it isn't often the date printed on the packaging.
