Cool @cptbilly, did you pick it up at auction? It's a great piece of history.

It's not in the same kind of capsule as seen earlier in this thread. Photos:   Search: "VTG New York World's Fair 1964 Irradiated Dime Atomic Energy Commission" to see the listing " Even a clock that's stopped is right twice a day. "

I picked up one of those a while back. The holder is a slightly flexible plastic/rubber - the dime can actually be removed from it. I could have rotated the dime in holder before taking this picture.

The Museum of Atomic Energy also "encased" irradiated dimes in these plastic holders. These were undoubtedly from the same general time as the NY World's Fair ones.

Pretty cool, but since the dimes can easily be removed from the holder, there is virtually no way to determine if the dime was the originally irradiated dime. From the link provided by Hondo Boguss: https://www.coinbooks.org/esylum_v14n52a10.htmlEven though when exposed, the silver in the dimes changed from Ag-109 to the Ag-110m isotope and decayed via beta emission into Cd-110, the amount of Cd-110 created was microscopic—not enough to significantly alter the composition of the dime, so I believe it would be undetectable today some 60 years later. Still a really cool piece of history. |

Nice cptbilly & Hondo. I don't have the world's fair version yet. I will be on the lookout for one!
When I was kid my dad used to tell me to go in the bathroom with the lights out and I would see
the irradiated dimes glowing in the dark. Never did experience that phenomenon.

That we did, and flattened many a coin on the tracks. My friend took a deflecting quarter to the forehead one time, from a passing high-speed commuter train 4-5 stiches for that one. Those were the days! |
