silver south africa penny

In running through some of my older coins that i had collected back in the 60's i have what appears to be a 1960 1d from south africa. According to my krause they were minted in bronze. This appears to be plated in silver. Any comments

Unless a coin is an extremely scarce issue, alterations done outside the mint almost always result in the complete loss of any numismatic value. There may be some value as a novelty, but then again, maybe not.
