We present you the rarest and most expensive stamps, but this is not an all-encompassing set. Various nuances, such as a secret mark or a curl, not obvious and not evident at first sight, can make an ordinary stamp expensive.
So not every stamp that looks like a stamp that appears on this page can be that expensive. If you want to identify your stamp that looks like one of the stamps on this list, you need to check all of its varieties (this information is available to our subscribers on our website).

Most valuable Japanese stamps
Western fascination with Japan has existed since at least the mid-19th century, when the country (after 300 years of isolation) became open to the world. This significant event happened during the Meiji period. Around the same time, the country established the first national post office, which began printing its own stamps in 1871. Since then, Japanese philately has been very popular, both within local and foreign stamp collectors. Japan released many attractive issues, most of which relate to the major political shifts taking place in the country. There is a great variety of interesting Japanese postage items available on the market. However, it is really difficult to come by the unused stamps due to their popularity among local philately enthusiasts.
