Silver, Gasoline and Taxes

In 1961, gas prices were $ 0.30 per gallon. In 1961, a dime was 90% silver. It took three dimes to pay for one gallon of gas in 1961. Today, one of those 1961 silver dimes, are approximately worth $2.40. So if, the amount of silver, contained in a dime, will today, buy you 50% more gasoline today, than it would have in 1961, did gas prices really go up? Or did the government print so much money, that your money is just worth a lot less? There are the taxes you see... and there are the taxes they don't want you to see...
