Hey Harth, this response is specific to you.
In my almost 40 years of collecting, I have heard this question a lot.. a lot. The question you asked, is not really being answered, because you asked a "relative" question, which means you're gonna get a different answer from most every person as everyone has a different opinion. You might want to make your question a bit more concise. Basically, you asked which countries do you think stamp collecting will go up? When you say "good, long-term investments," you immediately bring up 3 separate subjective terms.. what do you mean by "good?"... by "long-term?"... by "investments?"
Thanks Brian for your great post which add more value to our discussion. so we can have more great feed back.As with any investing, this is a two part thingy. Investing is research and opportunity. Investing is usually 90% perspiration and 10% luck. Luck is buying a piece of land in the mountains to live quietly, and being unlucky is finding gold on it.. though some would call that "a good investment."
I think if you make 5% -10% of your buying stamp collection each year that is ( good investment )
Let me ask you, young man... what do you mean by "good?" is 10% over 20 years good? 50%? 100%? 300%? to Glen here, good is getting a collection that he can break down and sell at 200% in a couple of weeks. Good to me would mean to break even... lol... after 40 years and massive inflation. So, what do you mean by "good?"
Now, "long term." a week? a month? 2 years? 10 years? or 40 years in my case?
I will say 5 Years is long term investment. not 40Years. If 40 years is the case, I suggest you're gonna see rise and fall of empires, which will all dramatically effect the value of the stamps of those countries. if you want to say "good, long-term" money.. would tripling your money in 2-3 weeks work for you? if that is all you want, I can show you how to do that without leaving your computer, chair & desk.
Yes it will be nice to tell us how can we do that??? Check out the word "arbitrage."
No clue about #arbitrage # please let me know
Have you wondered yet why all the Chinese are buying Chinese stamps on eBay? Why Indians are buying Indian stamps on eBay???
Not realy please let us know ???Now the key word.. "investment." That generally means to "buy low, sell high." After you do your homework/research, you have to go out and find the opportunities. Where do you seek your opportunities? What have you researched? Hopefully this site isn't your reference material or only source of study. I mean it's good and fun, and that's why I am here, but you need to be a member of the APS (or the like) and dig through their philatelic library. If you're an American, you're in luck.. more opportunities here than any other place on the planet, in general. So, again, I ask, where do you buy? from approval companies? brick and mortar stores? shows? auctions - live or online? clubs?
What about buying stamps from the Post Office with face value and keep it as hoby and sell some of it when there is chance to make profit out of it .
I know some dealers buying stamps with face value from the P.O. with face Value and sell them at Ebay and at shows with an extra 20% up to 100% when it become out of stock at the Post Office.
But of you buy from auctions house or buying stamps as rare ones you have to take the risk of you want to buy it as an investment . but if you rich enough and you buy it as collectors then risk is out of your plan.when you answer those questions, we can go into what makes a country worth researching. Every country will have stamps that will go up in value, and some stamps that will go down in value.
finally, harth, I can pretty much assure you that if you live in the USA, pretty much all of your stamps will go up in price, but maybe not value. That is called inflation, and you're looking for a hedge against it.
If you're looking to continue the discussion... I will be here.
brian (my real name).
here's a test of research.. what do you think about this 'investment'???

I could show you about 100 of these from the same collection, but these two are good enough.
