It's actually still legal tender at face value, but all large denomination bills were withdrawn from circulation in 1969, and none had been printed since 1945. Fewer than 400 of them are known to still exist, and are worth far more to collectors.
You can, but they haven't been printed since the 1940s, and were withdrawn from circulation in the 1960s. They're still legal tender at face value, but worth considerably more to collectors.

A dollar bill has a mass of 1 gram. A modern US quarter has a mass of 5.67 grams.

$5000 bills were printed in limited quantities over a period of about 80 years, so it's not possible to provide a specific estimate without knowing its date. In any case, assuming your bill is genuine its collector value could be at least 3 times its face value and possibly more, so it should be examined in person by a reputable dealer or appraiser.

It doesn't. A dollar bill has a mass of 1 gram. A modern US quarter has a mass of 5.67 grams.
Please look at your bill more closely; the date should be 1934. There's more information at the question "What is the value of a 1934 US 20 dollar bill with HAWAII on it?"
well see... there are numbers on a bill and in your case it is... $20
There are many different kinds of dollar. Do you mean a dollar bill, a new dollar coin, an old dollar coin? Please post a more specific question.
