Silver coins of the 1572 type were minted with PHILIPVS IV and a 1/2-real cob was added to the usual 1, 2, 4, and 8-real denominations. There were major gold deposits in Colombia; a mint opened at Santa Fe de Bogotá in 1620, and it produced the first gold coins (cobs) in Spanish America in 1622.
Most issued silver coins in denominations of 1 ⁄ 4, 1 ⁄ 2, 1, 2, 4 and 8 reales and gold coins for 1 ⁄ 2, 1, 2, 4 and 8 escudos. Exceptions were the Santo Domingo mint, which did strike maravedíes in the sixteenth century and the Caracas mint which issued fraction of real copper coins in the early nineteenth century to facilitate commerce.

Frederick the Great issued the Friedrich d'or pistole of 5 thalers in 1741 while the gold-silver price ratio of 14.5 was low, making it cheaper to reissue the thaler currency in gold. At 6.05 g fine gold per pistole, each thaler was worth 1.21g fine gold & 1.21 x14.5 = 17.545 g fine silver, cheaper than the prevailing standard of 19.488 g fine ...
Bertrand's box paradox: the three equally probable outcomes after the first gold coin draw. The probability of drawing another gold coin from the same box is 0 in (a), and 1 in (b) and (c). Thus, the overall probability of drawing a gold coin in the second draw is 0 / 3 + 1 / 3 + 1 / 3 = 2 / 3 .
While the Olympic medals are a customary gift for winning athletes, this year's awards also have a special touch to them: Each gold, silver and bronze medal has an 18-gram hexagonal piece of iron ...
The doubloon (from Spanish doblón, or "double", i.e. double escudo) was a two-escudo gold coin worth approximately four Spanish dollars or 32 reales, [1] and weighing 6.766 grams (0.218 troy ounce) of 22-karat gold (or 0.917 fine; hence 6.2 g fine gold).
