How to tell whether a Soviet stamp is valuable

Stamps · 3 September 2026

Five things decide the value of a Soviet stamp: the print run, the perforation, printing varieties, the cancellation and the condition. Age alone decides almost nothing – issues from the 1960s and 1970s were printed in millions and are worth pennies, while a variety of an ordinary issue can outweigh the rest of an album. Everything starts the same way: find the issue by its catalogue number.

The five signs that matter

1. Print run

The main one. Soviet stamps were printed in enormous quantities: commemorative and thematic sets ran into millions and still sit in albums in hundreds of thousands of homes. What counts as scarce are small runs, official and service issues, and copies that were withdrawn before sale.

2. Perforation and imperforate versions

The same design was often issued both perforated and imperforate. The imperforate version usually had the smaller run, so it is valued higher. Measure carefully: margins trimmed with scissors turn an ordinary perforated stamp into a damaged one, not into a rare imperforate.

3. Printing varieties and errors

Colour shifts, missing ink, inverted elements, a different paper shade – each is a separate catalogue position. Varieties create the biggest gaps in valuation: an ordinary stamp and its error version can differ by orders of magnitude.

4. Overprints

In the first years of Soviet post, issues were frequently overprinted with a new face value or text. Always verify an overprint against the catalogue: forged overprints are far more common than forged stamps.

5. Cancellation and condition

For most issues a mint stamp with intact gum is worth more than a used one. The exception is the early period of 1918 to 1923, where a genuine postal cancellation proves the stamp actually went through the post. After that it comes down to condition: thin spots, tears, hinge marks and fading cost more than collectors expect.

Finding your stamp by catalogue number

Soviet issues are numbered in the CPA catalogue, and the number is tied to a specific issue and year. That number is what tells an ordinary stamp apart from a variety.

The collectioner.art archive holds 6,382 Soviet issues from 1918 to 1991, each image stored together with its CPA number. Two ways in: the Soviet Union page in the world catalogue, or the full catalogue with filters by year and series.

Once you have identified the issue

• Match the design, face value and year – all three, or it is a different issue.
• Check perforation and colour: one number can cover several variants.
• Hold the stamp against the light – thin spots and repaired tears show immediately.
• Do not rush to sell: check at least two independent sources and completed sales, not asking prices.

We deliberately quote no figures. Market prices depend on the individual copy and the venue, and any "average" number is misleading. The point of this guide is the set of signs that let you tell an ordinary issue from a scarce one yourself.
