Is Coin Shrinking a Safe and Fascinating Hobby?

[Pocketwatch]

It seems to be an interesting hobby. Might be a little dangerous though if you aren't careful with electricity.

Go ahead and debunk it. Who wants to be first?

I think the coins are aliens in disguise made by extraterrestial technology just waiting for their moment to overtake humanity ... you conviced me or was that myself :/

Isnt defacing currency illegal?

I am very skeptical about this process. This would imply that either a significant amount of metal has been removed, or if that is not the case, then the smaller coin has then same mass as the original, therefore the density has been been changed.~^ If this is the case something very strange has happened.

I suspect a hidden lost wax casting machine.

Has this process been repeated by independent labs?

I don't doubt it can be done like they say. If I had all the capacitors and step up transformers it takes, I would shrink some coins myself. Other metal objects can be shrunk as well.

The mass of the coin remains the same. According to them, it is legal.


Here is a good page that describes the process.

But why would a person want to shrink coins?

From those links, it looks like there is significant thickening. That makes sense. The magnetic forces would cause a stress that could be relieved by a reduction of surface area to volume ratio.

Judging from their price list of shrunken coins, it could be quite profitable. Especially since it seems very few people are doing it.

I found out about coin shrinking while I was searching for a way to compress time.

I am more interested in time compression than time dilation.

Hey, time is money!

I agree. The force obviously acts on a vector from all points on the circumfrence toward the center. The circumfrence shrinks, the center thickens. Mass and volume are conserved.

It doesn't seem that amazing...i'm not so sure that someone good with a hammer couldn't shape a coin anyhow without machines.

I haven't seen any shrunken coins on ebay.
