Mom used to can, something different each year. I remember we would eat (for example) Peaches for several years even though she only canned them one year. Ditto for other stuff.
We kept our canned stock in the "fruit cellar" which was a sub-basement in the house. Always dark (no windows), always cool.
I would say as long as they were kept in a dark cool place and the seals are intact you should be OK!!
