What is octagon shaped coin?

There are several octagon shaped coins that have been minted throughout history.

One of the most famous octagon shaped coins is the 1915 Panama-Pacific International Exposition coin, which was minted to celebrate the opening of the Panama Canal. The coin features an octagon shape with a design on each of its eight sides. The obverse side includes an image of Minerva, the Roman goddess of wisdom and sponsor of the arts, while the reverse side features an image of an eagle perched on a branch with its wings spread.

Another octagon shaped coin is the 1787 Brasher Doubloon, which was minted by the goldsmith Ephraim Brasher. It is one of the rarest and most valuable coins in the world. The coin features an octagon shape with the New York state eagle on one side and the initials "EB" on the other.

The Royal Mint in the United Kingdom also released a series of octagon shaped coins between 2017 and 2019 as part of their "Great British Coin Hunt" collection. These coins feature different designs on each of their eight sides, and were released in limited quantities to encourage coin collecting.

Octagon shaped coins are a unique and interesting addition to any coin collection, and their unusual shape makes them stand out from more traditional round coins.
