Tesla coils are the technology that has been researched since I was in Nuclear Engineering Grad school in the early 80s to confine the fusion reaction. There are huge forces generated. The amazing thing is how then can be balanced so evenly to uniformly collapse the coins. --Jerry

So does it change the density of the coin's metal?
My neighbor collects (moderns) and I gave a matched date pair of Ikes to him for Xmas . One reg. and one shrunken. Don't lose sight of the fact that you can send your UHRs in to be shrunk too.

Outstanding question! My wager is that since no metal is "lost" during the process, yes, the SG of the metal must be higher now.
But, an even better question....are they still legal tender???

Since the weight/mass doesn't change and the size/volume does, then it stands to reason that density [which is defined as mass per unit of volume] does change. Since the weight of each is the same you probably wouldn't notice it.
<< <i>So does it change the density of the coin's metal? >>
The density change would be very small, the equivalent of density changes from additional work hardening of metal that has been previously work hardened during the strike. Actually, the heat generated could have an annealing effect that can slightly decrease the density of the metal.
Temperature changes can slightly change the density of metal, depending on the coefficient of thermal expansion for the metal. Work hardening and annealing density changes are less than thermal changes.
The coins increase in thickness, but the specific gravity change would be nearly immeasurable.

I wonder with the science behind it if you shrink a silver coin down are you loosing silver content since its in a smaller coin now. or is the silver just more compact into a smaller area. Im sure its the same unless electrons were removed during the magnetic shrinking but i was just wondering.

No, the density of a metal is a basic elemental property that cannot change appreciably. I haven't seen one of these but I would say it is thicker. The forces try to push everything toward the center and the forces are greater as you get farther from the center. So each element of the coin gets moved toward the center by a force proportional to it's distance from the center (probably some exponent of r but I don't recall). So as it gets pushed toward the center it gets thicker. --Jerry
I had this done a few years ago while they were still cheap ($12) and I wanted one from 1997. I think the higher denominations will be too thick to properly fit into a slab. Maybe?

The ebay description says its thicker, but I wonder why they don't show an edge shot. So if the volume doesn't change then of course density doesn't either.

It is real. I know 'cause I have one that was shruck with a Tesla Coil.

<< <i>Very cool. Send it in to see if they'd put it in a genuine slab
That might be a vewry cool idea!!! I have a Morgan that they did about 8 years ago!!

Zapped and shrunk
I have one... forget what it is.
I think there is a rule, this topic must be resuraected every 18 months.....

And for those of you awaiting an answer.... I checked. My coin is a Mississippi State Quarter.

Does the shruken ASE shown still weigh 31.1 grams?
EDIT: How about stretching an ASE to the dia. of 5"?

Agreed. There is no loss of metal, weight is the same.
Back when Bert was first selling these he agreed to shrink some coins I sent him. I had him do a Walker, JFK and maybe something else.
