Check out the stamps on this envelope that was sent from Charleston to Columbia in 1850! During this time, the postal service operated on two tiers. One stamp was worth 5 cents – the fee to send the letter from Charleston to Columbia. The next stamp, worth 2 cents, would get the letter from the post office to the recipient. On October 3, this envelope will be actioned off by a New York auction house and is expected to bring in $20,000-$30,000! Check it out for yourself here.
