What is the value of a 1930 US quarter?

Answer 1

Look on the front of the coin to see if there's a small mint mark letter at the bottom of the pedestal with IN GOD written on it. It may be blank or there may be an S. (The M on the other pedestal is the designer's monogram and not a mint mark.)

Numismedia lists the following approximate retail values as of 04/2012:

No mint mark (Philadelphia):

Very worn condition - $9

Moderately worn - $13

Slightly worn - $14

Almost no wear - $75

Uncirculated - $132 to $2,150 depending on quality

"S" mint mark (San Francisco):

Very worn - $9

Moderately worn - $13

Slightly worn - $16

Almost no wear - $79

Uncirculated - $132 to $1,500

"TRVST"This spelling is NOT an error. Like many coins of the time, mottoes were lettered using the Roman alphabet which only has 24 letters. "V" was both a consonant and a vowel in Roman usage.

DISCLAIMER: The retail values quoted are the best available as of the date shown, but may vary significantly due to changes in the precious metals market. Also the wholesale (buying) price of a coin will be less than the selling (retail) price. A reputable coin dealer will be able to give a more accurate valuation based on inspection of the coin.
Most have heavy wear and retail values of $3.00-$7.00, better circulated coins are $15.00-$30.00 coins with light wear run $50.00 to $80.00
