In 1873, the authorized weight of the dime was raised slightly from 38.4 grains to 38.58 grains, the latter figure equaling exactly 2.5 grams. To signify the change, small arrowheads were placed to the left and right of the date on the dime (as well as the quarter and half dollar). Dimes minted in 1873 prior to the change, appear without arrows. The second With Arrows format was employed from the latter part of 1873 and all of 1874. After that time, the weight remained the same but the arrows were discontinued. The design otherwise remained unchanged.Sufficient quantities of business strikes were made so that any numismatist should have little difficulty locating coins in any grade from Good through AU. Uncirculated pieces are available, but in only about half the quantity of the earlier 1853-55 Arrows type. Survivors of the Proof coinage, which totaled 1. 500 coins for the two years, can be found although superb examples are scarce. Within the business strike mintage, the Carson City i ssues are low mintage, and tough to locate in any grade. They are prohibitively rare in Uncirculated condition.
