Congress established " Federal money' on the decimal plan in 1786; but twenty years elapsed before its use became at all general, and Pike treats it as something of a curiosity. English money was our standard. In that denomination accounts were kept, and until after the first decade of the nineteenth century, it continued to have prominent place in our arithmetics. Coins of many kinds were current during the early years of the republic, and the school children had to learn the comparative value of these moneys. Besides Federal money, there were four varying currencies issued by the individual states. Then there were English and Irish coins, and the Continental Johannes, Pistoles, Moidores, Doubloons, etc. The labor involved in the computation of ordinary business transactions at this period was appalling.
