    Yes, There are real coins out there like this. I can't speak for the
    products coming from Edmunds, but as a passionate amateur scientist
    who has built devices capable of shrinking coins and producing other
    facinating effects, I can say in the first person "yes, been there,
    done that". These instruments are producing huge amounts of current
    and dumping it all in one catastrophic blast. Depending on the coil
    or other device the current is dumped into, various effects can be
    obtained, from the shrinking of coins, the crushing of cans (or
    cutting them cleanly in half). Very dangerous stuff to mess with if
    you are not familiar with high voltage devices, but they certainly do
    exist. A web search on High Voltage Devices will bring up hundreds of
    sites maintained by obsessed HV enthusiasts. I believe another site
    offering the coins for sale among a lot of other strange materials is
    United Nuclear - My son bought me a plexiglass block which had a high
    current dumped through it (an insulator) and the discharge pattern is
    captured for ever inside the block. 

    If you are of the scientific (geek) type, you can apply many
    techniques to metals to yield all manner of results and no one else
    will be able to figure out how you got a piece of metal to do what it
    did! Take a look around the web but please seek professional advice
    before going anywhere near this type of equipment, or attempting to
    build it. Your home current is about 30 amps and can kill you, so
    100,000 amps will not only kill you, but have the same effect as
    jumping on a grenade. 

    A bit off topic for metalsmithing, but interesting just the same. 

Best Regards,
Jim DeRosa
