This coinage date is the second of just four early dimes to exceed the one million coin mark with a mintage of 1,215,000 dimes. While 13 varieties are known from a combination of nine obverse and 10 reverse dies, one of these die marriages (JR-10) is only known in Proof. This JR-1 variety is quite common, however, in higher demand due to its separate listing in the Guide Book. Perhaps the Guide Book notation of "rare" for this Rarity-2 variety could be revised.

Only use of the obverse die. The reverse was earlier used for 1824 JR-2, 1825 JR-4, and 1825 JR-5.

The reverse has an extremely faint die crack from rim to left wing tip, just left of U and another very light die crack from the upper right curve of D to the border over extreme right edge of this letter.

This is the so-called 1827/5, however, specific attribution as an overdate remains unverified. A discussion of this variety by David Davis appeared in Volume 2, Issue 1 of the Journal.
