KM-58, 1964 South Africa (Republic) 2 1/2 cents in proof; silver, plain edge; this small coin was an equivalent of three pence during transitional policy of moving from the pound to decimal monetary standard, only minted for 4 years (1961 through 1964), these are most affordable in 1961 where over 200,000 were minted and in 2064 where regular mintage was small but proof is abundant at 16,000 units, sparkling perfect proof, nice to look at
