The Ottoman Empire coins are some of the most beautiful in the world and as a result of that, they are in great demand. Coin collectors everywhere want Ottoman Empire coins! It all began when Osman Gazi minted the first coins of the Ottoman Empire. This Empire had not quite been established then, but never the less, Osman Gazi announced his name in Anatolia.
This first coin was called the "Akche" - a coin distinctive to the Ottoman Empire and was basically minted from silver. The "akche" was used as currency in the Ottoman Empire till well within the fifteenth century and there was no devaluation of it either.
Subsequently, the Ottoman rulers began to change the style and design of the "akche". One distinctive feature of the Ottoman Empire coins is that they featured always, the signature of the Ottoman Empire ruler. Orhan Gazi after the fifteenth century started to mint the "akche"s in a very different style, called the Ilhanli style. This was probably due to pressure from the Ilhanli of Anatolia. These coins predictably featured his signature.
In addition to this, they also featured a short prayer after the governor of Timurtis died. But generally Ottoman Empire coins did not have long prayers on them. They featured basically the name of the Sultan, the mint date and the minting location. There were short prayers and blessings engraved on the coins.
After the "Akche" came the copper coins which were known as the "Mangir". These Ottoman Empire coins came into being during the rule of Murad I, who was the first Sultan to step onto European territory. The Mangir, though made of an inferior material were actually one of the most colorful of Ottoman coins. They were minted for local use basically and they were actually sub units of the "Akche".
Then came "Mehmed" the Conqueror, under whom the Empire flourished and gold coins were minted. These Ottoman Empire coins were called Sultani and were minted in Venice Dukedom scale and also had a separate weight so as to avoid any confusion during trade. The "Akche" and the "Mangir" were then only minted in certain areas of the Ottoman Empire.
Then there was the "tughra" which was an elaborate monogram that featured the name and title of the Sultan. All the Ottoman Empire coins were beautiful and exquisite - the fact that they are in great demand everywhere in the world even today bears testimony to that.
