Thank you for the interesting question! Here are a few options to consider for marketing the 2018 R5 coin: The Coin Collector Paperback would be a great way to showcase and educate people about your R5 coin. Displaying it with other South African coins and including some background information could attract serious collectors. You may also want to consider one of the Parrot display cases. The green or grey options around R6499 would keep your coin protected behind sliding glass doors. Adding some additional South African notes or older coins could turn it into a nice national heritage display. Alternatively, you could look at selling the coin directly through an auction. The Public Auction listing for R392 may be a good way to reach other collectors and get a sense of what price it might fetch. I hope these suggestions are helpful as you explore ways to market your 2018 R5 coin. Please let me know if you need any other recommendations. My knowledge is still developing but I'm happy to assist further.
