Unique Collection of Famous British Stamp Errors

Stamp collecting is all about attention to detail.

Serious collectors are like detectives looking for anomalies in stamps everywhere they go.

And for good reason…

There’s real money to be made in finding errors on stamps as you will see shortly. 

You would think with modern automated printing processes, we would no longer see stamps coming out with printing errors.

Yet, the reign of Queen Elizabeth II is considered the golden era of British stamp errors. 

But they are not meant to exist…

Our Postal Authorities have several layers of quality control in every part of the printing and production process.

Despite all their efforts, sometimes things go wrong and oversights happen.

Our postal workers are, on the whole, fairly diligent.

They do ensure only an extremely limited number of stamp errors slip through the net and reach the general public. 

The fact they are so rare and often visually appealing is what makes them so desirable. As Mark Twain said: 

“In order to make a man or boy covet a thing, it is only necessary to make the thing difficult to attain.”

In today’s world I would be quick to add that this is not a gender-specific trait!

Because of this innate human trait, some stamp collectors focus entirely on building a collection of errors. Most collectors want to own a few errors at least, often becoming the main feature point of their collection.

So, it should come as no surprise to hear this area of collecting has seen some exciting growth in value over the past 20 years.

For sure, the emergence of the internet in this modern era of stamp collecting has brought this area of collecting to the forefront. 

Over the years, I have witnessed often feverish bidding activity both online and at auction.

Collecting stamp errors is an area of philately understandable to a much larger audience than some of the more complex areas of collecting.

Furthermore, they remain relatively affordable and accessible to a large number of collectors enabling a vibrant market.

Now is the perfect time to buy

Whilst I watched prices rocketing in some years, over the past five years, prices have, at best, remained static and many British modern stamp errors have fallen in value.

Yet, over the past 20 years, prices have still risen significantly despite the recent hiatus.

Some of these modern British stamp errors have grown in value by 10 times over this period.

Because of the recent lull, they are now starting to look temptingly under-valued.

With growing uncertainty in the economy and financial markets, I expect to see a new wave of interest as people look for alternative ways to invest their cash.

We are also seeing new collectors coming in to the market chasing these very scarce errors.

I think the pieces are coming together to bring about the next wave of growth.

A great collection and an even better investment opportunity

With this in mind, I have spent some considerable time putting together a collection for you comprising modern GB stamp errors.

The collection represents my TOP 10 recommendations for both pleasure and investment.

These are stamps I think have a good chance of delivering strong growth over the next 20 years.

You can view the entire collection here…


The collection comprises 10 visually stunning British modern stamp errors and is available for you to purchase today for the price of £46,500.

The table below provides you with a summary from an investment perspective:

Some important facts you need to know about this collection:

  • It provides a strong representative sample of modern printing errors spanning the period 1964-1998
  • All stamps in the collection are in pristine mint condition with full original gum
  • The total collection shows historic growth over the past 20 years of 342% (17.7% pa)
  • The best performing stamp recorded growth of 780%. The worst performer still increased in value by 118%
  • They are all very scarce with a limited number of examples in existence
  • It would be nigh on impossible to replicate this collection such is the combined rarity factor in seeking to assemble the constituent parts
  • I have focussed the collection on stamp errors where their current values appear low in the context of their market capitalisations (ie. value x number of possible examples). This is, in my view, a critical factor to focus on when theorising future growth potential

Some technical information

The collection includes three main types of printing errors:

Missing colour errors

Missing colours in stamps occur usually when part of a multi-run printing process is missed.

In general, the more striking the effect of the missing colour, the more valuable the stamp error. Sometimes missing colours can lead to major design features being omitted entirely.

There are more missing colour errors in modern stamps than older stamp designs. This is because earlier stamp designs featured fewer colours (often only two) so were much easier to notice.

Imperforate errors

Imperforate errors are sometimes referred to as a perforation error. They occur when the stamp perforations are missing from one or more sides of the stamp.

Because perforations can be removed by trimming, philatelists only collect imperforate errors in pairs or blocks of stamps. 

This kind of error occurs more frequently in automated coil printing methods where there is less opportunity to identify for faults. The stringent checking of stamps printed in sheets mean such imperforate examples are far rarer. 

Inverted watermark

Watermarks are used to give stamps a distinctive appearance and to prevent counterfeiting.

Watermark inversions on stamps occur when a sheet of watermarked paper is fed into a printing press upside down.

Because they are less obvious and more difficult to detect, they are of particular interest to collectors where hidden value can sometimes be found previously unidentified in collections.

Some Highlights

Take a look at some highlights from the collection…

A Spectacular Rarity of the highest order

Great Britain Queen Elizabeth II 1966 4d Birds (Ordinary paper), SG696ab.

PRICE: £20,000

A superb unmounted original gum left hand marginal block of four with black, blue, bistre and reddish brown omitted, offered with normal block for comparison. 

The error results in the loss of value and inscription on all stamps. Also affected are the gull's head, wing detail and water shading; the blue tit's feather detail and branch shading; the robin's wings and legs; and the blackbird's body and legs.

The error existed in a cylinder block of eight but was split into two blocks of four in the late 90's. As a result, there are only two examples in existence.

A wonderful example of undoubtedly the most spectacular Queen Elizabeth II error.

This is one of the most exceptional British stamps you could possibly own.

It looks good value when compared to the 1976 13p Roses error valued at £150,000 where there are three known examples.

Much, much rarer than its price

Great Britain 1990 29p Rabbit 150th Anniversary of the Royal Society for Prevention of Cruelty to Animals (RSPCA), SG1480a.

PRICE: £5,500

A superb unmounted mint, full original gum bottom marginal gutter block of four containing one completely imperforate pair and one pair partially perforated.

Very scarce and the only imperforate gutter block of four we have ever seen.

Pierron records only 5 mint examples making this an exceptionally rare error.

It is excellent value at this price with the SG catalogue price for a basic pair listed at £5,500. This rarity is far more special than a basic pair.

Looks undervalued

Great Britain Queen Elizabeth II 1998 26p Comedians "Eric Morecambe", SG2042ea.

PRICE: £600

A superb unmounted original gum example with vermilion printed double.

Due to insufficient tension between the printing plate and rubber cylinder or the rubber cylinder and paper, it's possible for an image to be transferred two or more times.

So called kiss prints occasionally occur at the beginning or end of a print run.

Pierron records only 30 mint examples.

At a price of just £600, this unusual error looks undervalued.

To put into perspective, it has a market capitalisation of just £18,000 for the 30 mint examples. This means it trades at a third of the value of the rest of the collection based on market capitalisation.

How to order

The British stamp errors collection is available to purchase for the price of £46,500.

I am offering a unique opportunity to acquire a fantastic range of British Queen Elizabeth II stamp errors.

This area of the stamp market has proven its worth through historic performance and has promising potential for future growth.
