If by bimetallism you mean the idea that gold and silver should both circulate freely, that is the correct view. But if by bimetallism you mean what 99% of people at the time meant by the term, which was letting gold and silver circulate at a government-imposed ratio — X silver coins will be equal to one gold coin — then no.
Market forces invariably deviate from any government-imposed ratio, with chaotic results. This is why a single metal was chosen as the standard. (The better solution would have been getting government out of money altogether.)
