Some of these varieties germinate surprisingly well if they have been stored properly, even if they are over 10 years old, but others do not.
Should I soak my corn seeds before planting?
For the best germination rates, wait until the soil temperature is at least 65 degrees Fahrenheit, and soak the corn in water before planting. This speeds the first stage of germination, the uptake of water, for the hard-coated corn seeds.

Water test: Take your seeds and put them in a container of water. Let them sit for about 15 minutes. Then if the seeds sink, they are still viable; if they float, they most likely will not sprout.
