Looked at my insurance companies website (State Farm) concerning this and it states:
-----------------------------------------
Is your car eligible for coverage?
If you’re not sure, these definitions may help:
Classic Automobile: A motor vehicle ten or more years old, which is rare or of special historical interest because of exceptionally fine workmanship or limited production. A classic motor vehicle 25 years old or older is covered as an antique.
Antique Automobile: A motor vehicle 25 or more years old.
And here are some important conditions for eligibility:
Your antique or classic car must be used on a very limited basis, such as exhibitions, club activities, and parades or similar events. You need to have restored, maintained, or preserved your antique or classic car.

I drive mine too much to qualify for this.
