I'm sure they all worked at one time, or they never should have left the factory.
You'll get better results if you actually test them, to let the buyer know he isn't getting one that has been fried on 120 volts.
Restored mechanically & physically (and should also be restored electronically) are often in the eye of the beholder. Many "restored" radios are simply partially repaired sets or poorly refinished cabinets. Also it is important if it has been recently restored as opposed to being restored sometime in the past where it actually needs a fresh restoration again.
Place an ad in the classifieds either here or over at the Antique Radio Forum which has much more viewership when dealing with radios. Use good pictures and descriptions. Price them as what they are worth to you. If they sell, you've done okay. If they don't, either they may be undesired or overpriced (or both).
Better yet, sell them in person at a local radio club meet. That way the buyer can see firsthand what you are selling and you don't have to ship a radio and deal with an unhappy buyer when they've discovered that your description did not meet their reality.
Good luck.
