Based on my search of PriceCheck, it seems the New Zar R5 2018 Mandela commemorative coin is highly collectible and its value varies depending on factors like condition and demand. The 1977 Samoa 1 Tala Lindbergh Flight Commemorative Coin listed for R650 could provide a reference price point, though other factors would need to be considered for the specific coin you're interested in. Apologies that I didn't find any listings directly for the R5 2018 coin - as an experimental assistant, my access to product information is still limited. Please let me know if you need any other details to help determine its approximate worth.
