what would 30 pieces of silver be worth today
Thirty pieces of silver The word used in Matthew 26:15 (ἀργύρια, argyria) simply means "silver coins,"[9] and scholars disagree on the type of coins that would have been used. Donald Wiseman suggests two possibilities. They could have been tetradrachms of Tyre, usually referred to as Tyrian shekels (14 grams of 94% silver), or staters from Antioch (15 grams of 75% silver), which bore the head of Augustus.[10] Alternatively, they could have been Ptolemaic tetradrachms (13.5 ± 1 g of 25% silver).[11] There are 31.1035 grams per troy ounce. At spot valuation of $17.06/oz (the closing price on Monday, December 12, 2016), 30 "pieces of silver" would be worth between $185 and $216 in present-day value (USD).
Gold standard This was meant to be a temporary measure, with the gold price of the dollar and the official rate of exchanges remaining constant. Revaluing currencies was the main purpose of this plan. No official revaluation or redemption occurred. The dollar subsequently floated. In December 1971, the “Smithsonian Agreement” was reached. In this agreement, the dollar was devalued from $35 per troy ounce of gold to $38. Other countries' currencies appreciated. However, gold convertibility did not resume. In October 1973, the price was raised to $42.22. Once again, the devaluation was insufficient. Within two weeks of the second devaluation the dollar was left to float. The $42.22 par value was made official in September 1973, long after it had been abandoned in practice. In October 1976, the government officially changed the definition of the dollar; references to gold were removed from statutes. From this point, the international monetary system was made of pure fiat money.
