Monaco. 10 Francs 1966 (No reserve price)

Here you have one of the most coveted coins in world numismatics: a 1966 Monaco 10 francs commemorative coin, minted in silver (.900) to celebrate the tenth wedding anniversary of Prince Rainier III and Grace Kelly. Coin details: It features the joined profiles of Rainier III and Grace Kelly on the obverse and the inscription "GRACE · RAINIER III OF MONACO · 1966" on the reverse.
Based on visual inspection of the photograph, the coin appears to be in excellent condition, estimated between EBC (Excellent, Good Conservation) and UNC (Uncirculated). Being stored in an acrylic holder, it seems to have been treated as a collectible piece protected from the wear of ordinary circulation. And indeed, just as the AI says. The coin is in an excellent state of preservation. As if it had just come from CECA, and it also has a mintage of only 24,000 pieces worldwide, and I assure you it will be extraordinarily difficult to find another specimen in a similar condition. It is a 50-year-old coin with a proof strike, and it is very hard to keep such a coin immaculate.
