One aspect I find most fascinating about the Roman "debullionization" of their coinage was how they gradually diluted the gold/silver bullion content of their coinage. And further, how at one point it was decided that previously 100% silver coins went to 40% Ag---irresistably reminiscent of 1965-1969 Kennedy Halves.
Other than affecting the meltdown value of the coin itself, I can't get too excited about it.
