I thought this was interesting: According to Google, In Georgia, a license plate issued in 1989 or earlier can be used on a vehicle of the same model year. The vehicle must be registered for the current year with a Georgia license plate or decal.
To register a classic car in Georgia, you can:
Bring the authentic historical license plate and a completed form T-224 Authentic Historical License Plate Affidavit of Ownership to your local county tag office.
The county tag office will issue a current license plate and registration.
