My Father was presented with one of these medallions, the accompanying letter reads: The Ministryof Foreign Affairs is honoured to present a small memento in the form of an Erasmus Medallion to the Allied War Vetrans who are visiting the Netherlands in 1984 to commemorate the allied invasion of Europe and fighting in the Netherlands forty year ago.
The Latin text on the reverse translates as:
"Constancy is not always to say the same thing, but always to persist in the same thing".
Hope this helps.
