I'll gave a go at a more formal identification of the group. Be aware that any prices I'm quoting are from a slightly old book (2004 for coins from the 1800's, 2006 for coins from the 1900's); Russian prices are unpredictable, depending in large part on how much "free money" the wealtheir classes in Russia have at any give time. The catalogue values are historically, quite low compared to actual prices realised at auction or on
ebay.
1: Russian Empire 1 kopek 1852, EM mintmark. Less than a dollar in this condition.
2: Russian Empire 3 kopeks 1903. Common, but this one appears to be rasonably good condition. I'd say a $3 to $5 coin.
3: Russian Empire 50 kopeks 1896. The "with star on rim" variety (struck in Paris, France) catalogues at $20 in my 2004 edition Krause book; this could well be one of the highly-sought-after scarcer types whose value could fluctuate wildly. The "without star" is listed at $8.
4: Russian Empire 1 kopek 1899. With that greenish tinge, probably less than a dollar.
5: Estonia 1 sent 1929. Less than a dollar in this condition.
6: Nazi Germany 10 reichspfennig 1941 G. Zinc. In this condition, it's basically scrap value, a few cents.
7: Russian Empire 20 kopeks 1914. Common, but made of silver. A few dollars.
8: Nazi Germany 5 reichspfennig 1941 A. These coins are made of zinc, and rarely preserve this well. Still, it's a very common coin; probably worth a dollar or two.
9: Estonia 1 mark 1926. Probably worth less than a dollar in that condition.
10: Russian Empire 10 kopeks 1913. Only a few dollars, even though it's in very good condition.
11: Exactly the same as #8, only much worse condition. This one's scrap.
12: Nazi Germany 1 reichspfennig 1941 A. A few cents in this condition.
13: Russian Empire 5 kopeks 1891. Common and worn, but still 25 cents worth of silver.
14: Estonia 3 marka 1922. Less than a dollar in this condition.
15: USSR 20 kopeks, I can't quite make out the date; I think it's 1932. This design was used from 1931 to 1934. Less than a dollar in this condition.
16: I can't even tell what it used to be. I can see a shield from a coat of arms, making me think one of the Germanic states, perhaps (given the Baltic flavour of most of the other coins in this grouping) from the Livonian or Teutonic Order, or the Swedish territories which used to be there in that part of the world.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
