These include the series key 1916-D, the semi-key 19-D, and the 1942//1-D overdates. The Mercury dime series does not boast many key dates, semi-keys, or rare varieties, but those that it does offer are quite valuable. Uncirculated coins with a grade of MS 65 can sell for around $25. In uncirculated condition the price is around $6 for coins with an MS 60 grade. In extremely fine condition the value is around $3.25. The 1944 dime with no mint mark is worth around $3 in very fine condition. Most circulated Roosevelt dimes are only worth their bullion value. In 1964, the mint made the last dimes containing 90% silver. The later dates are mostly common even in Uncirculated condition and can be found in rolls even today. No dimes were issued during the depths of the Great Depression (1932-33) since there was less need for coinage then.
