What is the difference – Open Edition, Limited Edition or Numbered Series ?
Open Editions are produced in an unlimied number from the date of issue until retirement year. Limited Editions are produced in limited number from date of issue until sold-out. The number of units to be made is decided before introduction and purchase includes a certificate of authentication. Numbered Series is produced from date of issue until its retirement date, but numbered in a non-limited form. Purchase includes a Numbered Certificate.
