It is a nifty piece of exonumia from the Atomic Age, I have a Mercury dime in that encasement and a Roosevelt in the 1964 World's Fair plastic disc. Someone that sells that many coins on ebay should know better than to call that an Ike dime... Edited by biokemist6

Here's an old thread about irradiated dimes. The "nice toning" mentioned by the seller is a by-product of the neutron bombardment; a small amount of the silver in the coin, particularly near the centre where the beam was most intense, has been permanently transmuted into cadmium. Pure cadmium is chemically more resistant to oxidation than silver, but the silver-cadmium "alloy" created by this process can give funky colours. Irradiated dimes often show this circular toning pattern; the longer the coin was in the beam, the stronger the effect.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis

my grandfather had a few of these things in his collection. I thought they were pretty neat when I first saw them because I had never heard of them before that time. his wasn't as rare as a "Ike dime" but I liked them

Unless they had a different method of irradiating them in the early years there was no "beam". When I made mine in 1967 at Oak Ridge, you put your dime in a slot, it rolled down a channel in a tank of water and halfway down it stopped next to a neutron emitting piece of radioactive metal. After about thirty seconds it would continue rolling down the channel and drop into the receiving tray. You then put it into the white plastic ring, placed it in the aluminum holder, put the clear plastic window in and put the whole thing into another slot where it was crimped slightly to hold the window in place. You could then pass it by the geiger counter and listen to it chatter. So no bean just irradiation by being in contact with a radioactive source. |

Don't you know they took Roosevelt off the dime and put Eisenhower on it for 1948! Hahaha ;)

Still...it's a real souvenir from the Atomic Age, but no longer radioactive.
