The coins have been issued in two runs, with the first batch of 290,500 produced in November.

Varying in value, gold coins are worth ₩30,000 (£20/$26/€22) and ₩20,000 (£13/$18/€15).

Silver coins, which showcase the "ice and speed" disciplines, are worth ₩5,000 (£3.30/$4.40/€3.60) while brass coins featuring snowboard, figure skating, skeleton, luge, biathlon, ice hockey and curling have a value of ₩1,000 (£0.66/$0.90/€0.70).

They are designed with images that represent Pyeongchang 2018 and the seven Olympic winter sports.

Pyeongchang 2018 President Lee Hee-beom as well as honorary ambassador and Vancouver 2010 figure skating champion Yuna Kim attended the launch event.

Orders to purchase the coins can be made from tomorrow until September 29 at 11 financial institutions.

It is hoped the commemorative coins and notes will help boost awareness of the Games in South Korea.

South Korean President Moon Jae-in bought tickets for the Games last week after it was revealed that only 22.7 per cent of tickets available had been purchased so far.

This figure is thought to mark the lowest in recent Winter Olympic history at this stage of preparations.

Only 4.85 per cent have been sold in South Korea, even though it was forecast that the host nation will account for 70 per cent of the overall total.

A total of 1.18 million tickets are available for the Olympics.

It is hoped that 90 per cent of this total, so 1.07 million, will be sold beforehand.
