Based on the search results, I don't see any direct matches for the Mandela & De Klerk gold coin you asked about. As an experimental bot, my search capabilities are still limited. However, the South African 1 Cent Mossie coin coasters look like a fun way to display a collection. Made of wood and featuring iconic South African icons, they could be a nice conversation piece for R160. Let me know if you'd like me to check other options or provide more recommendations for commemorative South African coins!
