FREE: Irradiated Dime - 1964 NYC Worlds Fair

The listing, Irradiated Dime - 1964 NYC Worlds Fair has ended.

Dime Irradiated at the Atomic Energy Commission exhibit at the NY World's Fair 1964 or 1965,
The photos you see are online references, not my souvenir, which is also in very good condition.

ORIGINALLY 90% Silver, NOW over 45% Cadmium as a result of irradiation. A metals test by a precious metals dealer should show this is NO LONGER a silver coin! You can see it's a Roosevelt dime, but the Cadmium has become so tarnished I cannot make out the date. I have made NO attempt to clean this coin.
It CAN be removed from the soft plastic souvenir holder, but that is part of its value. Similar dimes from the AEC Oak Ridge Lab in Tennessee CANNOT be removed from their holder, according to online references you can find with Google.

This could be an added curiosity in your coin collection, OR a show-and-tell item for class study of atomic energy.

(Warning: if allowing others to handle it, leave it in a clear plastic bag or coin holder. It is not dangerous, and I understand the residual radiation is hard to detect, but it can be a pleasing historical possession that you don't want to lose.) )

I could not choose a value, but I found an eBay seller asking over $50 for theirs. I have set free shipping to simplify the transaction. You will not be disappointed!
