PROOF Coins Commemorative

Commemorative PROOF coins, special issues by Imprensa Nacional Casa da Moeda (INCM), minted from 1977 to 2001 with issues in escudos. These commemorative coins have issues minted in various metal alloys, some of which were minted in cupronickel, BNC Silver, PROOF Silver, PROOF Gold, the normal issue coins came out without their own packaging and all Special Issues, almost entirely in precious metals, were released in their own wallets or cases and respective certificates of authenticity. The PROOF finish is easily distinguished, as the coin has a shiny mirrored background and high relief in a matte finish.
