all I know is that yes it is very niche, but it has been going for many years, so there must be something in it.
that's what I thought, and the internet gets so overwhelming sometimes, that I thought I wld just ask.
fair enough buddy.
I think it's more of a hobby...unless you get some really really rare like 1800s stamps which are worth a fortune, then it's not like you're going to earn loads, more of a "love of the job" type thing
I read that you're looking at roughly 5.4% gain over 3 years...so not actually that bad...but it's something you defo have to be into. So if you are, then it sounds perfect for you!
I would research the right people to go to, and if you are already into stamps then you should already know who to speak to. The investment sounds as boring as the hobby (no offence lol) but it's steady eddies who win in the end so why not!
