Here is a 1986 Portuguese 25 Escudos "Admission to the European Common Market " coin in my opinion of  Extremely Fine grade to possibly the uncirculated grade. A coin most likely obtained from the Portuguese mint and placed straight into a Portuguese coin collection
Only two in stock 

 
  • Fine (F): Worn over whole area, but only the highest spots are worn completely through. (US: VF-20) 
  • Very Fine (VF): Detail clear, but obvious evidence of very limited circulation. High spots worn but detail remains. Traces of mint lustre may linger amongst the letters of the inscription. (US: EF-40)
  • Extremely Fine (EF): Slight wear on high spots on close inspection, and all other detail clear and sharp. Much mint lustre may remain. May appear uncirculated to the naked eye. (US: MS-60)
  • Uncirculated (Unc): No wear at all, although it is possible for the design not to be fully struck up in the minting process. There may be bag abrasions. Older coins may be tarnished or toned.(US: MS-62 to 65)
