You shouldn't use the older canning jars for several reasons. They may "explode" when the cool air hits the jar as you move it out of the hot water or at any time during the cooling down period. They may not seal well and the food could become contaminated or poisonous. The bottom could simply "fall off" in the water during the canning process, releasing the food within the jar out into the water. Also, the older jars were not made for pressure canning and may not withstand the pressure.
