Roger Federer Head on a coin

A commemorative silver coin depicting tennis champion Roger Federer has proved so popular that the Swiss Mint's website has been paralyzed.

The coin, with a face value of 20 francs ($20), is the first by the federal mint with a living person on it.

The Federal Mint, Swissmint, will issue a 20 Swiss francs silver commemorative coin in his honor in January, the news outlet reported.

Federer has won 20 Grand Slams and he is regarded as one of the best players to have ever stepped on the tennis court. In 2007, Swiss Post released a Roger Federer stamp in his birthplace of Basel. These records, as well as his versatile playing style, make him probably the greatest tennis player of all time. He has taken 20 major titles - the most in history by a male player- and has been ranked world number one for a record 310 weeks.

The obverse side of the coins is designed by Artist Remo Mascherini, Flamatt, in the canton of Fribourg. The inscription of ROGER FEDERER is placed along the upper-right edge of the coin. The Swiss coin gesture was not the first time Federer was honored in a special way.
