Ottoman-era coins are being offered for sale for millions of Turkish Liras on e-commerce platforms, with a gold coin dated 1223 from the period of Mahmud II up for sale for 500 million liras and 10 coins dated 1327 from the reign of Mehmed V for 50 million liras.

Historical Ottoman coins have been put up for sale in at least 17,000 online advertisement posts.

Prospective buyers should consult with an expert before making any payments, said Neşet Gündüz, the head of the Consumers' Association in Antalya.

"Not every object from the Ottoman era necessarily has a historical value," he said.
