I've got a raw kennedy half that was reduced almost to quarter size by scientific means....pretty cool talking piece.
I forget the forum member I bought it from (I think it was someone on the forum when I first joined) but I recall they were a bit of a rage for awhile...I got in on it, but I still like it.
There was a webpage but I can't remember it.
Here's a different webpage I just found. Not sure of the "magnetic force" that the one you linked to is about, but this is a similar thought and I do recall a 3rd tier TPGS was willing to slab these way back then....
its really insane what they do... Ive seen it.... they wrap the coin up in copper wire and then hit it with a huge amount of electricity from charged up banks of capacitors the result is a really loud BANG and flash... its done in a bulletproof glass type enclosure and the copper is blown away and the coin is shrunk from the magnetic forces created.... Im sure you can read about it online... freaky
The coin isn't actually shrunk. The diameter is reduced with the thickness slightly increased while the weight and volume of metal remains the same.

is there an official x, y, z axis we can designate to the diameter, thickness and whatever the other would be.
by that standard, we could say it was reduced(shrunk) along the whatever axis but was increased along another, while the mass remained virtually the same. (unless shrunk is inclusive to all axis while mass is unchanged. although shrinking something should include mass too, no?) another one of those words with loose interpretation depending on context/usage.
dont know about density. guess it would need be specified along certain axis as well.
Originally posted by: SaorAlba There is a process called spark erosion where you can shrink metal items down - it usually works best on dime or cent sized coins though.
Spark erosion is used to make counterfeit coin dies. Not to shrink coins.
Here is a good video of it that was on the page Bochiman linked to. About the middle it is shown close-up in a 100,000 frame per second recording and takes only 4 frames to shrink.

Here is one source with a good explanation:

Shrinky dinky
I've been told I tolerate fools poorly...that may explain things if I have a problem with you. Current ebay items - Nothing at the moment
You may purchase their coin to be shrunk or provide your own coin of choice.

They're pretty cool.

My girlfriend wouldn't be happy if I stood too close to that machine while it was running......
Is this what Bochiman was talking about?
