Yes - and it depends on if it is hybrid and non-hybrid. Open pollinated heirlooms seed will last much longer and be more viable than hybrids.
Our Master Gardener group has proven as much in the tomatoes we grow. We grow them for several purposes - sell at plant sale (we sell a couple 1,000 tomato plants each year), use them in our demo garden, for Tomato fest and pure trials for KU. Last year we grew like 72 types and we cut back this year to ~ 50 or so.
The hybrid seed cost much more and come with fewer seeds in a bag - of which we buy very large size. Some of the heirloom seed packs will easily last us 2 - 4 years.
