Scarcity, and being able to prove that you went there and got your dime irradiated.

Anyone could press a dime into a fancy container, but a fake could be easily detected with a geiger counter. There was no other way to irradiate dimes at the time.

>The only activity that might be detected today would be due to trace quantities of Ag-108m, but it would require long counts and relatively sophisticated equipment. I could not detect any in the three coins in the collection.
