Is it true that a spinning coin's wobble rate increases as the coin loses energy, a behavior described by the Euler's disk effect?

Yes. Multiple peer-reviewed sources and a reference article state that a spinning coin or disk's precession (wobble) rate increases or diverges as it spins down and stops, matching the Euler's disk effect.
