SAMPLE 10 gold Sobieski 1933 - MIRRORED
IIRP sample struck with a mirror stamp, without the inscription sample.
Coin with a specific serration, characteristic of IIRP mirror samples.
Great presentation, natural beautiful patina.
Note with CAMEO inscription - the coin's mirror stands out strongly from the coin's matte relief.
The highest note in the NGC for a coin with the CAMEO annotation.
Mintage of 100 pieces.
A rare and beautiful coin.
Definitely recommended for the best IIRP proof collections.Literature: Parchimovich P153b
