Here are the notes I took about the coins in that lot:
1. 5 K., 1757, silver -- nice little specimen in XF/AU, I thought maybe $200
2. Paul I rouble, 1798-СМ/МБ -- grade XF detail, rim ding
3. 25 K. 1829-НГ (I first saw "ПГ" on this one ... perhaps an error coin with missing crossbar on the "H"??) -- grade UNC+, very nice wings-down type
4. 25 K., 1858-ФБ (grade UNC) -- little black spot at 6 o'clock under eagle
5. 25 K. 1859-ФБ -- grade UNC
6. Poltina 1861-ФБ -- grade XF
7. Poltina, 1887 (grade AU/UNC) -- very nice coin (I estimated at least $400 for this one alone)
8. 25 K., 1896 -- grade UNC
9. 50 K., 1896-АГ -- grade VF
10. 25 K., 1900 -- grade AU/MS (my estimate: $300)
11. 50 K., 1913-BC -- AU (nothing to write home about, but problem-free)
12. Poltina 1922 (UNC)
13. Rouble 1924 (UNC)
There should be 14 coins, I but I don't have any notes for more than these 13.
