I agree with your
attribution. Your coin is almost certainly from the same
obverse die as the
CNG specimen you link to and the one illustrated by
Varbanov. The
reverse dies too are very similar and may be the same.
The coin is indeed very
rare. It is not in the corpus of coins of
Pautalia published by
Ruzicka in 1933.
Varbanov publishes
his specimen as "Unpublished, Very
Rare". Moreover it is an unusual and interesting
reverse type.
Unfortunately, despite the
rarity and interest of the
types, the market value of your specimen of the coin is low, because of its
poor condition.
