When did you last pay to receive a letter? Never, probably. But for a long time in Britain, that's exactly how mail worked. The recipient paid, and the amount depended on how far the letter had travelled and how many sheets of paper it contained.
The system was expensive and strange. A letter from London to Edinburgh could cost many times what a labourer could spare, and a second sheet of paper could double the price. People got inventive. Some wrote on both sides of the page, crossed their lines, or agreed on coded markings on the outside of the letter so the recipient could read the news without paying: a tick, a smudge, a particular fold, and the letter was turned away at the door.
A man with a spreadsheet
Rowland Hill, a teacher and reformer, looked at the postal accounts in the 1830s and came to an uncomfortable conclusion. The cost of carrying a letter was tiny. Most of the expense was in handling: collecting payment from the recipient, working out distances and recording everything by hand.
His proposal was simple. Charge a uniform low rate by weight, regardless of distance, and have the sender pay in advance. Prepayment would be shown by a small adhesive label stuck to the letter. After a public campaign and some resistance from the Post Office, the plan went ahead.
May 1840
The Penny Black went on sale in Britain in May 1840. It showed the profile of the young Queen Victoria and cost one penny. A matching two-penny stamp followed. The design was printed in black ink, which turned out to be a poor choice, because red cancellation marks were hard to see on it. A year later it was replaced by the Penny Red.
The early stamps had no perforations, so people cut them apart with scissors. Perforation came in the 1850s, after machines were developed that punched rows of small holes between the stamps.
The effect on volume was dramatic. Letter traffic in Britain rose sharply in the years after the reform, and an ordinary person could now afford to write to a distant relative. Mail became part of normal life, not a luxury or a legal matter.
It changed the shape of the letter itself. Before the reform, a separate envelope counted as an extra sheet and doubled the postage, so people folded and sealed the letter itself and wrote the address on the outside. Once the price depended on weight, envelopes became cheap and sensible, and within a few years machines were turning them out by the thousand.
Copying a good idea
Other countries watched. Some Swiss cantons and Brazil issued stamps in 1843, and within a few decades the practice had spread across Europe, the Americas and beyond. Today almost every postal service in the world uses some version of the idea, even as physical letters decline.
The sender-pays principle matters as much as the stamp itself. It meant the postal service got its money before doing the work, and it meant nobody could refuse a letter to avoid paying. The little paper rectangle was almost a side effect of that change.
What's left of it
The Penny Black is not as rare as people assume. Millions were printed, and used examples still turn up in collectors' markets at fairly modest prices, though good unused copies are worth far more.
What stays interesting to me is how small the original idea was. No new technology, no invention, just a different answer to the question of who should pay and when. Plenty of modern problems have similar boring solutions that nobody tries for decades.
