Ecuador (struck in London or Germany), copper-nickel 2 sucres, 1973, NGC MS 65. KM-82. This unassuming coin has an interesting backstory: Some 2 million pieces were struck by either VGM Metals in Germany (Llantrisant Mint) or the Royal Mint in London for general circulation in Ecuador. However, the design was not approved, the order retracted, and the bulk of the mintage was melted down. Very few are known to have survived this mass melting; sources suggest around a 100 or fewer extant pieces. A Gem coin with faint golden toning.
Estimate: $200 - $300
