There probably then needs to be another coin type (bronze piece?) below c.p., to fill the gap where c.p. used to be. Without that you probably lose too much granularity.
Compare with pre-1970's Britain - the standard unit was a pound, below which you (commonly) had shillings and pence, with 240p to the pound...which made for a very granular system...but not granular enough, thus the need for ha'pennies (1/2p) and farthings (1/4p). Only having one coin type below the standard unit simply isn't enough. Lanefan
You could have another coin type below copper, but it is really unnecessary. Only a few items and services are listed as copper in PH (gold standard) and they are easily adjusted by giving multiples for a copper (eg 1 candle = 1cp in RAW, so 10 candles for 1 cp on the silver standard, same with torches: 10 for 1 cp) or rounding up (even a tankard listed as 2cp (gold standard), could easily be 1 cp in the silver standard world).
The truth is that adventuring characters spend none of their careers at the low end of the monetary system. First level characters start with 20-200gp (gold standard). It doesn't take more than a few levels before copper is completely irrelevant and isn't worth the weight to carry or the time to count. Unless the DM handwaves everything, most characters without a stingy money characteristic from their background will just start leaving the copper on the ground, or maybe that was just my players
