CT allows it too as long as the plates are in good condition (able to be read and not faded or rusted bad). CT requires you to get the antique plates first (called Early American here) then you can fill out a form and get the old plate(s) (YOM, Year Of Manufacture) connected to your Early American plates. Your registration is still the Early Americans and they must stay registered but you can display and drive with the YOMs showing.
The Ealry American plates MUST stay in the car, under the seat, in the trunk, somewhere so that if you do get stopped and an officer asked to see the real plates you can furnish them along with the registration for them. The DMV also has a letter you keep in the glove box that says you've been aproved to display the YOM plates.
Now it does get tricky with antique plates with possible limitations different states put on them. When I got my Early Americans I was told of no limitations verbally or written 9 1/2 years ago when I got them. Now I hear people saying you're not allowed to tow a trailer with a vehicle that has them, I don't have a trailer so I never looked into it. Some states only allow the vehicle to be used for parades and shows only while others limit the vehicle from traveling 100 miles or more from where it resides.
I did a little searching and found this

You really have to contact the DMV and find the requirements and limitations of running with the different plates.
