With much interest I read the contributions about the irradiated dimes in the latest issues of The E-Sylum. Irradiating dimes was not done only in the US. I have an example from the Netherlands. It is made of greenish-white, probably at one time fluorescent, and black plastic. Encased is a 10 cent coin of Queen Wilhelmina (Type 4, issued 1926 - 1945) made of 64% silver. The encasement has a diameter of 25 mm. The inscription on the Obverse reads: KON.WILHELMINA FONDS - RIJN IN RAI 1952. The Reverse reads: RADIOACTIEF GEMAAKT DOOR NEUTRONEN - BESTRALING (made radioactive by neutron irradiation). On the white rim the name of the manufacturer is written: LUXOR PLASTICS N.V. HOLLAND in small letters, not visible in the photograph.
The exhibition "De Rijn in de RAI" took place from 21 may until 15 june 1952 in Amsterdam. It was held because of the opening of the Amsterdam-Rhine Canal in that year. The major feature was an indoor model of the Rhine, 200 meters long, 10 m wide and 1 m deep. The Purpose of the Queen Wilhelmina Fund was to fund research into cures for Cancer. It was started in 1949. The encasement was probably issued to raise funds.
I would be interested to learn if irradiated dimes (coins) were issued as souvenirs in Other Countries.
Great question - I was not aware of irradiated coins from other countries. Does anyone else know of any other outside the U.S.?
