Question: I discovered my great-grandmother's brother was a local postmaster in Maine. Can you tell me where I can find out the cost to mail a letter in the 1870's to 1910's? His diaries discuss the rate changes, and I thought it would be helpful to follow along with a list.
Answer: This website provides the costs for U.S. Postal rates for letters and postcards from the 1860's to present - http://www.akdart.com/postrate.html
