2025 Cameroon The World's Most Expensive Stamps Mauritius Post Office 17.5g Silver Coin

In 1847, two stamps inscribed “POST OFFICE” – One Penny and Two Pence – were issued in Port Louis. Of the 500 copies of each denomination, only 26 or 27 are known to exist today, depending on the source. Most remain in Museum and royal collections, which is why they appear on the market extremely rarely. This silver coin preserves the original colours and typography, highlighting one of philately’s most coveted subjects.
