The first coin is from 1811 or 1911? If it is from 1811 is 10 Kopeks from Alexander I (1801-25) and it's made of silver. If its from 1911 is from Nicolas II (1894-1917), made of silver too. About the 2nd coin looks like 1 Kopek from Alexander III (1881-94). Cupper.
Ah Gee guys, I knew that one. And that isn't often. Maybe next time I get in first if someone has a question on Zuid Afrik Republic Shillings.
These are regular 10 kopecks 1911 (Nicolas II) made of silver. In Russian auctions you can buy it for $1-2. And 1 kopeck 1889 (Alexander III) made of copper. $0.5-1. Nothing special...especially because of quality.
