Stamp collecting is a very popular hobby and famous free time activity.
The most expensive stamp is the 1-cent Magenta stamp of 1856. It was bought for $9.5 m and you can see it on top of this article.
To start your stamp collection you need a special album to keep your stamps in and of course stamps. You can buy them at a post office or ask your parents and grandparents to give you some if they have any.
A good idea is to ask your friends to send you a postcard when they travel to another country. This way you will also collect stamps from other countries.
I started my collection in 2010 and I now have 179 stamps. My favourite stamps are the ones you can see here:
