What is the value of a 1937 US quarter?

Answer 1

Look on the back to see if there's a tiny mint mark letter above the R in QUARTER. Numismedia lists the following approximate retail values as of 02/2010:

No mint mark (Philadelphia):

Very worn condition - $3.85

Moderately worn - $3.97

Slightly worn - $4.03

Almost no wear - $15

Uncirculated - $23.00 to $780.00 depending on quality

"D" mint mark (Denver):

Very worn condition - $3.85

Moderately worn - $3.97

Slightly worn - $5.75

Almost no wear - $30

Uncirculated - $51.75 to $2210.00

"S" mint mark (San Francisco):

Very worn condition - $3.85

Moderately worn - $6.90

Slightly worn - $14.95

Almost no wear - $81

Uncirculated - $138.00 to $2470.00
The coin is worth about $3.25 just for the silver, the collectible value depends on how much wear the coin has.
