I have an extensive collection of Norman Rockwell plates that I wish to sell, but don't know the current value of any of them. Is there information as to their value that you can refer me to?

Yep, as others have said, check with the museum and eBay too!

Go on e bay. See what they sell for

I would call the museum

I think the best bet is antique road show if it is still there. Or try calling the museum as others have mentioned. No harm in calling them. They are very good people.

You may wish to call the museum.

You should contact the Norman Rockwell Museum. Someone there might be able to help.
