Stampless thalers make up only a small percentage of the pieces that have survived to our time. They are sought after and valued regardless of their state of preservation, and collecting a set of signatures in the unstamped version is quite a collector's challenge for many years.
Here, additionally, with Zamoyski's signature - the second most rare for a single-dollar coin. By M. Kozlowski recorded only 17 pieces with this signature, where the rarest is 16 pieces and the commonest as many as 65.
Piece with pronounced ferruginous efflorescence in the paper (the so-called " phoxing", more on the subject on theUMK website), nevertheless the bill is all-natural and without any conservation treatment.
An item of a completely different and higher status. It is a piece remaining from circulation and never reported (not surrendered) to the Central Liquidation Commission - without its stamp on the back.
Very rare.
