Gold Reef City   Gold Reef City is a large amusement park in Johannesburg, South Africa. Located on an old gold mine, the park is themed around the gold rush on the Witwatersrand. Park staff wear period costumes of the 1880s, and the buildings on the park are designed to mimic the same period. There is a museum dedicated to gold mining on the grounds where it is possible to see a gold-containing ore vein and see how real gold is poured into barrels.       Location Johannesburg, South Africa, Website http://www.goldreefcity.co.za/ Slogan: The City Without Limits     There are many attractions at Gold Reef City, not the least of which are water rides and roller coasters. The liveshows of Idols South Africa are filmed live in the "Hippodrome", a large auditorium based in the park. Gold Reef City is located to the south of the Central Business District off of the M1. It is also the site of the Apartheid Museum.   Mint mark: GRC (Gold Reef City) South African Krugerrand were produced from 1987 to 1991. I got the above 1/2 Pond and 1 Pond brass coins along with South African PS117 (8 coins) [featuring the bust of President Vorster in 1982] in the same box from Haroon Tareen. I have also seen a 1 penny 1993 featuring a rhinoceros coin sold on ebay. These brass coins are probably patterns and could not be made into gold coins as the Gold Reef City mine was closed as it run out of gold.     Micro-Nations   Chiefa Coins
