The rarest valuable stamp
By Metro Creative
The most valuable rare stamp in the world is the British Guiana 1c Magenta. The stamp was auctioned in 2014 and sold for $9.48 million, though that price tag dipped considerably when it was auctioned again for a price of roughly $8.3 million in 2021.
According to Invaluable.com, the stamp was included in an 1856 emergency run that was produced after the initial shipment of 1c magenta stamps went missing. That emergency run included a small boat on the stamp, which can be seen in the lone remaining stamp from that run that is now so valuable. That lone stamp was discovered by a young boy in 1873.
Nearly 150 years later, the world’s most valuable stamp can be purchased via fractional ownership, a method through which unrelated parties can share in the ownership of a high-value tangible asset.
