What this coin looks like (obverse, reverse, mint mark location, special features, etc.): One major variety of the 1934 Washington silver quarter features a Light Motto. This coin can be identified by noting how the "IN GOD WE TRUST" motto on the obverse of the coin is blurry and nearly indistinct.
Variety Differences: The light motto is very weak and the letters are nearly indistinct due to a worn die. The medium motto has a strong strike with clear letters but the letters are thin just like the light motto. The middle of the "W" in "WE" is aligned lower than the tops of the sides of the letter "W". The heavy motto has a strong strike but the letters are much thicker and the middle of the "W" is aligned higher and lines up with the top of the sides of the "W". The difference between the light motto vs medium motto vs heavy motto is depicted below in the example comparison image of the coins:
