A very nice trojak which is a very rare "new minting" - A 19th century collector's issue, the so-called "novodiela".
Issued by the mint in Warsaw.
Priced 10 times more expensive in Berezowski than standard issues (4.00 zlotys to 0.40 zlotys).
Type with the initials of Frederick Hunger (FH by the tail of the eagle).
Very rare.
