China Changes Stamp Collecting Worldwide: How One Country Influenced Stamp Prices
The hobby of collecting stamps is not a new one, and it’s one that has amused and intrigued enthusiasts of all ages for years. The earliest recorded stamp collectors date back to the late 1700s, even before stamps were used for postal purposes. The pastime caught on and spread throughout the world after that, reaching a peak in the United States during the 1970s. Popularity has faded slightly since then, but the hobby lives on through all of us that still enjoy it.
The History of Stamp Collecting
Many point to Irish Receiver General of Stamp Dues John Bourke as the world’s first recorded stamp collector (1). At the time, he created a book of embossed revenue stamps and hand-stamped charge marks. His collection still exists today, carefully preserved in the city of Dublin, in the Royal Irish Academy.

You’ve decided it’s time to sell your stamp collection. Perhaps it was inherited and no longer interests you. Maybe you have outgrown the hobby or are unable to enjoy it anymore. Better yet, you have more valuable and rarer collections and you want to be rid of your amateur days.
Whatever your situation, you will want to review these tips for selling your stamp collection.
Where to Sell Stamps
In short, sell them at the same place you bought them. However, you may have collected them from your mail or they may have been given to you. Here are a few avenues to sell your stamps.

Foxing is that reddish-brown stain that appears on stamps. In reality, these are funghi that attack the paper’s cellulose fibres. Methods for getting rid of foxing are known for quite some time. Here, we shall use the publication of the Sociedade Filatélica Paulista from 20 of December of 2008 (by Sérgio Marques da Silva) as a reference.
The best known methods are those using potassium permanganate or chlorine-based products. With the new bleaches that do not contain chlorine, other ways of dealing with foxing have also been tried out.
1 – Potassium permanganate method
Potassium permanganate has its molecular formula KMnO4 . In its solid state, it presents itself as purple-bronze crystals and its solubility in water is 7g in 100ml (meaning 100%) at 25 degrees Celsius. With this proportion, the solution is saturated. If we use 2 grams in 200ml water, we should therefore have a solution of about 14%. This is sufficient for our experiments. The amount of time the stamp should remain under the solution varies on the degree of foxing contamination but, in general, 5 minutes should be sufficient. Using a higher concentration, the stamp should be dipped for less time.
