It is therefore conjectured that the dollar sign derived from a symbol consisting of a superimposing S and I or J that was used to denote the German silver coin. Such symbol appears in the 1686 edition of ''An Introduction to Merchants' Accounts'' by John Collins. Alternatively, the symbol could have come from a snake and cross emblem on the thaler coins.
