28 Most Valuable South African Stamps

My friend invited me over today to have a look at some of his most valuable South African stamp collections.

Let me tell you, it was something truly special. Some of his stamps were worth over R100,000 EACH, and the history behind each one blew me away!

Apparently, they can range from anything between a few hundred rands to R1.2 million. Anyways, it’s safe to say I’m hooked. I decided to get on board and blog about my research. This is why I’m sitting at my desk this second writing this.

The first step, I decided to research 20 of the most valuable South African stamps that money can buy.

One thing worth mentioning, the first thing my friend told me is that just because stamps are valuable, it doesn’t mean they are rare. There are many factors that come into play that affects the price.

Based on my research, here are 20 of the most Valuable South African Stamps.

Some stamp terms explained:

  • SG in the headline is Stanley Gibbons catalog code. The numbers that follow SG mean nothing, however, you can learn something from the letters that follow SG.
  • SGO means it was an official stamp that was only used by government agencies at the time.
  • SGD means the stamp was definitive. So in this case it would be an everyday postage stamp used by anyone that was sold for a long time making them less rare.
  • Mint means the stamp has never been used and is in the best possible condition.

*There are a few terms that I couldn’t understand such as ac/a, SGw, var, SGR and SGb. If you know what these terms mean please let us know in the comments below and I’ll add them to the list above.

Are Stamps a Good Investment?

There are two types of stamps. Collectible stamps that are collected by people interested in philately, and investment-grade stamps that are bought by investors.

What’s the difference between the two? Collectible stamps aren’t bought as an investment, even though they may appreciate, they are purely bought as a hobby.

Only a very small percentage of stamps actually increase in value over time. This is where the difference lies. The hobbyist doesn’t care; however, the investor will study and only invest in stamps that they believe are likely to increase in value.

So how do you know if a stamp will increase in value? Investors usually look at these 3 things when deciding if a stamp is worth investing in.

  1. The stamps must be extremely rare.
  2. They are in the best possible condition.
  3. Stamps that have mistakes on them offer an investment opportunity. The famous “Prussian Blue” is the perfect example. There are also some modern-day stamp mistakes that have turned out extremely profitable for investors. I guess printing errors make them rarer?!

Should I Buy Stamps As An Investment?

The way I see it is I’ll be researching stamps as a hobby anyway, so I might as well buy the stamps that I think are going to increase in price.

In other words, I’ll be a Stamp Hobby investor! Is that a thing? Well, it is now.

Where To Buy Stamps

Now that I’ve got my list, it’s time to find the most reputable company to buy from in South Africa. I don’t want to make the big mistake of buying fake stamps. There are a lot of places online such as bidorbuy and Gumtree however I would like to avoid this as much as possible.

  • East gate stamps and coins seem to be the most legit company in the country from what I’ve seen online. They are even verified by the mint to sell Krugerrands, so they have a solid reputation.
  • Stanley Gibbons is another online store that has a solid reputation for selling high-quality stamps online. They’re situated in the United Kingdom, so if you’re reading this from overseas you’ll probably get your stamps a lot quicker if you order it from them.

There are also several auctions that are held throughout South Africa. I’ve never been to one but apparently, some of the more expensive stamps are sold through here. Visit philatelicfriends.co.za to find out about the latest stamp auctions. Who knows, I might see you at one of them! Just don’t steal my bid.

Where To Sell Stamps

Again, be careful. I’ve heard some bad stories of people getting robbed while trying to sell on Gumtree. If your stamp is cheap then Gumtree or BidorBuy might work, if it’s expensive definitely do an auction or go to a reputable company such as East gate stamps and coins.
