I have planted "old" potatoes and had them grow just fine. Others say not to do it you may have disease spores on the spuds, but I haven't worried over it too much myself. If they don't look sick, they probably aren't if you have had them for a while. Usually if they don't have any lesions on the skins or other questionable spots, I don't stress too much about it...because if you can't eat them what other option for them is there?

I am glad there are those you can ask, but doing it for yourself is even better. take care.
