How much would one dollar in 1950 be worth today?

In 1862 the United States passed a law known as "The Legal Tender Act" as a part of this law was 'the Parity Act" which stated in relevant part that all legal tender will hold the face value of the note. So in essence a dollar in 1933, 1950 and in todays money is still worth the same because 'law' says it MUST be. The buying power of that money however does change, in 1950 a loaf of bread cost $0.14 per loaf today it would cost $2.00 per loaf (avg) - so if we use that buying power as a guide the dollar in 1950 was worth 7.5 dollars in 2009 (simplified).
