There are a few contenders for the most expensive coffee mug title. One is a 24-karat gold-plated mug created by Australian company Diakinetic. It costs $1,200. Another is a diamond-encrusted mug created by British jeweler Azature. That one costs $48,000.
But the most expensive coffee mug in the world is probably the one made by Russian artist Anatoly Konenko. His handcrafted porcelain and gold mug features a portrait of Vladimir Putin and is adorned with diamonds, rubies, and sapphires. It was commissioned by an unnamed businessman and cost a whopping $1.4 million!
