well I don't really know. they're different coins you see...
the 2003 10 roubles sheet you listed might be either
KM#817, 818, 819 or 800 (at least these are the 2003 mentioned in the catalogs)
while the other 10 roubles coin is clearly the KM#891 issue from 2005.
why do you think it should be deleted?
Hallo Andree,
till yesterday the number of this coin was Y#891.
Yesterday I saw, that the KM number field was not locked.
Therefore I removed the number.
Now this entry can be used for any other coin from 2003.
