It is
Dattari 5279 and likely not a variety of that number. What makes the coin interesting is the fact that it was struck by the same die carvers as the L Theta issues which were very
rare. This die carver issued other
rare year 10 issues such as the
Nilus Bust l., LI (
Curtis collection). The
palm in the
field on other specimens represents the
decennalia. In
Emmett, the
palm description on coins with eagles is included if it is
part of the motif (ie,
palm on wing -- even this may be a decennalis reference, but as this
eagle type occurs elsewhere where the
decennalia is not possible it was continued as a separate motif)
