The 1928 Mercury Dime is the end of a series of more valuable dimes. From 1928 onward the value for dimes drops unless it has an error. A Denver minted 1928 dime in uncirculated (MS-63) condition, will likely auction off for about $360. A Philadelphia or San Francisco minted coin in the same condition will likely go for $35-55.
