I've got two Russian 20 kopeks. Both are nice with remaining lustre, both could use an acetone bath - they're original and pretty crusty. I'd grade the 1880/7 as XF+ and the 1878 as AU. They look a lot better than my hurried photos indicate...if you'd like better photos let me know and I'll try to get some up later. $45.00 for the pair delivered. PM me if interested.

1878...this one has quite a lot of lustre under the grime.





1880/7...this one has less remaining lustre than the previous one, but has a neat overdate (the second 8 in the date is punched over a 7).
