Gold was $35 an ounce in 1933. So, $50K = 1428.57 ounces of gold. At today's prices, that much gold is worth $419.90 per ounce; so at a minimum, that would be $599,857.14 .
A serving of Coke was a nickle back then. Now, the average price is about 75 cents. On the Coca-Cola scale, it would be about $750,000.00
Not equivalent. In 1933 a man would work all day for one silver dollar and today silver is only $5.50/oz. $35 would represent an entire month's wages for many.
