1950-s ERROR....S OVER D MINT MARK

The 1950-D Washington Quarter is a 90% silver coin with a value heavily dependent on its condition and the presence of a specific, rare error. The standard coin has a base value derived from its silver content (its "melt value").

The most valuable version of this coin is the rare 1950-D/S overmintmark variety, where a "D" mint mark was clearly punched over an "S" mint mark die error during production.
Value of the D/S error: In circulated condition, this error can start around $34.00, but in pristine, uncirculated condition, examples have sold for as much as $17,500 or more at auction. This is a highly sought-after error among collectors.
