Just so you know: American 1-cent (penny) and 5-cent (nickel) coins are very close (that is, less than 50% error) to having nearly identical face and metal values.
It's a little harder, though, to get the same for 10 cents (dime), 25 cents (quarter), and especially dollars (which fall in that very border area where a silver coin is still a little too tiny, but a base-metal coin would've been way too huge if we're trying to keep metal value similar to face).
(Compare: British 1797 "cartwheel" pennies. Two pence, here's our dollar (1 gram silver, 70+ grams copper aka base metal). One penny, here's our half dollar (0.5 grams silver, 40ish grams copper - choose among those yourself). Halfpenny (not actually made in 1797, IIRC) - here's our quarter (way too tiny in silver, but relatively manageable in copper).)
For lesser (parts-of-cent) denominations, in case those exist, one could presumably use the Russian idea - plated stainless steel (as making plastic coins in under-cent denominations would probably result in something similar to Ankh-Morpork elims - that is, coins that are worth several dozen times face value to make).
