First day covers: what they are and what decides value

Stamps · 5 September 2026

A first day cover is an envelope carrying a new stamp cancelled on its first day of issue. It is three things at once – the stamp, the postmark and the printed design on the envelope – and each is collected separately. That also explains the disappointment behind most searches: covers were produced in enormous numbers for exactly this market, so being a first day cover is not by itself a reason for value.

The three parts of a cover

1. The stamp. The new issue itself, sometimes a single value, sometimes a full set. A cover carrying the complete set is a different object from one carrying a single stamp.
2. The cancellation. A postmark dated to the first day, often a special design made for the occasion and used only at a designated post office.
3. The cachet. The printed design on the envelope itself, thematically matched to the stamp. Some cachets were designed by known artists and are collected in their own right.

Because the three parts are independent, the same stamp can exist on dozens of different covers, and the same cachet can carry different cancellations.

What actually decides interest

• Completeness. The full set on one cover beats a single stamp from that set.
• The cancellation. A clean, fully legible special postmark, struck in the right place, matters more than the stamp. A smudged or half-missing strike takes most of the interest away.
• Genuine postal use. A cover that actually travelled – addressed, with a receiving mark – tells a story that a display piece never posted does not. Which of the two is preferred depends on the collector, but the distinction is always recorded.
• Condition. Envelopes are large thin paper: bends, browning at the edges and a torn flap all count. Covers were often stored in albums under pressure, so a flat, clean example is less common than it sounds.
• Who made it. Official post office covers, private cachet makers and hand-painted covers form separate categories with separate followings.

Why most covers are common

From the middle of the twentieth century onward, postal administrations produced first day covers deliberately for collectors, in runs sized to the collector market rather than to postal need. That is the whole answer to why a shoebox of covers from the 1970s and 1980s is usually a shoebox of common material. Age helps very little here: a 1978 cover exists in the same quantities today as it did then, because nobody threw them away.

The exceptions run the other way: early covers from before the practice became industrial, covers with cancellations from a place that used the special postmark for a single day, and covers where something went wrong – a wrong date in the postmark, a stamp used before its official issue date.

How to store them

• Flat, in album pages sized for the envelope – not folded into a smaller sleeve.
• Avoid soft plastic; use inert sleeves or acid-free paper.
• Do not remove the stamp from the cover: separated, both parts lose most of what made them interesting.
• Keep them out of light – the cachet is printed ink and fades like any other, as covered in the guide to storing a paper collection.

What the archive shows

The archive holds Soviet first day covers as objects rather than as stamp images – for example the cover of 1987 alongside the 1978 one above. They show the pattern clearly: a printed design on the left, the new stamp on the right, and a special cancellation tying them together. The stamps themselves can then be looked up among the 6,382 Soviet issues of 1918–1991 in the catalogue.
