PROOF Sets, Annual Series of Circulation Coins in Escudos

The PROOF Sets issued by the Portuguese Mint (INCM) comprise the annual series of Portuguese Escudo circulation coins produced in the highest‑quality finish, featuring frosted reliefs and mirror‑polished fields. These special collector editions were released between 1993 and the pre‑Euro period, presenting complete sets of the monetary systems still in use but struck with superior technical standards. In several years, the INCM included denominations that never circulated as everyday change, being minted exclusively for these PROOF sets or their BNC counterparts. Each set was issued in official INCM packaging and accompanied by a certificate of guarantee, representing the finest numismatic finish produced by the Portuguese Mint. This category gathers all PROOF Escudo sets issued by the INCM.
