The current editions of the Standard Catalog of World Coins and the Weltmünzkatalog list only plated steel (magnetic) varieties for dates 1996 EE and later, which would leave only 1969 EE types as non-magnetic. Do non-magnetic versions actually exist for later dates, or are these listings perpetuating an error in earlier editions of the SCWC?
