Colonial Rate Chart

Tables of Postage Rates 1765
Rate chart

The rates on this postal rate chart, which became effective October 10, 1765, remained unchanged until the American Revolution. The original rates, expressed in British currency, were converted by America's Deputy Postmasters General, Benjamin Franklin and John Foxcroft, to pennyweights and grains of silver so that postage could be computed in colonial currency. Charts such as this were displayed in local post offices.
