Im trying to figure out if these are proof coins or not and maybe a value on one? Any knowledge is greatly appreciated.

Mintage of the 55 1/2 penny was 3,774,000 and 2850 KM 45 prices seem to be all over the map. If a proof say 62/ 63 I see some real value if a mint strike the values seem to be under a dollar depending on condition. Back around 2008-10 I has some real sweet SA coins. Mint and proof sets that included the 1 and 2 rand gold coins. I parted with them to a former Rhodesian /S.A. person who had left S.A. and lived in Canada. At one time a thought to be good friend....turned out to be just the opposite.

Thank you for your knowledge. I have a few of them "like 30" even a couple with errors. Not sure what to do with them.
