I would say that at this moment, you would have a very, very small chance of any swaps.
You only have 23 coins on your swap list, which are only of 6 different coins, which are mostly quite common, and the fact that the cost of postage to South Africa would higher than all 23 coins are worth
You seriously need to greatly enlarge your swap list.
This is a personal view only
I'm just a collector of coins, not a slave to it, unless I am in a coin shop.
For all you banknote collectors. Link to my swap list.
