Have you ever looked at coins under a black light? What can you see that's not otherwise visible?

New collectors, please educate yourself before spending money on coins; there are people who believe that using numismatic knowledge to rip the naïve is what this hobby is all about.

Which only adds to the mental images that one can conjure up at the term..."filthy lucre".
I dug my old black light out from deep in storage. I had to clean it up. It was pretty rusty. After flickering for a while it finally lit up. That was the big experience.
But I didn't see anything unusual or noteworthy on the few coins I looked at with it... What am I looking for?

I'd like to know if there is anything to be seen. After all I went to some trouble to clean up my old black light.

Good for detecting starching to simulate crispness.

I use it mainly on pattery and old English ware to detect repairs.
Are there known uses on coins??

Black lights are basically a fluorescent lamp with a different sort of phosphor coating on the inside.
The coating absorbs the harmful wavelengths of ultra violet light (that cause sunburns) and emits only the long-wave (safe) ultra-violet light along with some blue and violet visable light.
The emitted UV light reacts with various external phosphors, such as the phosphors in laundry detergent, and causes them to "glow".
