7 3/4 inches in diameter.  Nice old porcelain plate showing scenes from Dixon Illinois - birthplace of Ronald Reagan.  

               

Domestic shipping and handling in the U.S. is $10.50.  Foreign bidders are welcome with the shipping costs to be determined solely by Ebay International Shipping.   I will combine shipping. I have decided to sell my collection of antiques (and other nice items), which I have been collecting for the past 30 years.  Good luck with your bids.
