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

    I'm not sure I want to know.

    Isn't that done to detect puttying?

    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.

    Wow! That was quite an experience.



    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?

    Am the only one who tried this?

    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. image

    used more on paper money.

    Good for detecting starching to simulate crispness.

    I posted a pic several months ago. No one was interested. I can post it again tonight.

    I use it mainly on pattery and old English ware to detect repairs.

    Are there known uses on coins??

    Forget coins for a moment. What do black lights show and what are the scientific principles at work? I'm sure Conder knows the answers, but perhaps some mere mortal will answer before he has a chance.

    Go buy a few rolls of circulated coins and see if they glow.

    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".

    Does this mean I'm going to die now?
