Here is a coin made in an edition of only 5 pieces!
An extremely rare technological sample of a ten-dollar coin with reverse design by Anna Jarnuszkiewicz. Made in aluminum, without the inscription of the trial, and also importantly, minted in a different year than the nickel trials of the "locksmith key and gear wheel" type. - 1958 instead of 1960.
Listed only once on the numismatic market (auction WDA 17/874 sold for 50,600 gold).
Beautiful mint condition.
Aluminum, diameter 31 mm, weight 3.54 g.
