Aldo,
Thank you for your welcoming message!
Very useful information, I was wondering if there is any web site that explains about previous issues technical specifications like diameter, weight ... as well as pictures and descriptions. I am just starting my euro silver and gold collection (I already have all commemorative and circulating coins, of all years that had even a slight change in the design, including changes in mint marks) ... so I am looking for a lot of information to start building a new era in my collection. To be absolutely honest, I am missing information from the countries: Greece, Italy, Luxembourg, Monaco, Netherlands, Portugal, San Marino and Vatican City).
If anyone can help me with sites with info, even in other languages, it will be very helpfull.
Thanks,
Miguel
