Note 3 — PART I
Z. Tamotsu Iwado translation
The value of gold pieces is hard to ascertain, as there were in circulation coins minted in different ages, and their qualities were of as different grades. However, one “ryo”, as the larger gold money was termed, is about equivalent to a hundred yen according to the present scale of currency and its purchasing power, or it is, at least, an approximation as near as needed for our present purpose.
