If the coins don't get denser, then they can't be shrinking. Moreover, is it not the case that the process is stripping away the surface of the coins, in an even manner, thus retaining the features but in a reduced size? The coil's disintegration is doing something other than compressing the coin, it is ablating the coin's surface in a uniform manner.

: If there were a way to wrap the coins in both directions, (where the
: flat
: and thin sides got equal emf compression at the same time{i'm sure there
: is}) would the coins become and stay more dense? If they became more
: dense could there be a way to make them harder and not softer like lead?
: Kind of an interesting thought that maybe nobody else might have had.
: A thought with potentially profitable implications.

: Hi Andrew,
: To my knowledge, there is no coil configuration (or any other process
: for that matter) that could be used to make the material in the coins
: permanently denser. This is due to the inherent physical properties of
: the metals and alloys used in coins. The coins do get tougher from work
: hardening and the surfaces show signs of plastic flow (radiating Luder's
: Lines), but the metals and alloys will not retain a permanently higher
: density state.
