This is a transfer die whose denticles have been marginally enhanced. This is a variety from the soon-to-be-published, and so-called TRANSITION family, the same family that famously created the 1874 AMERICU dime. This counterfeiter used a Seated obverse married with a very similar, but still slightly different Barber dime reverse, one of the few hybrid U.S. counterfeits in terms of coin design marriages ever recorded. While not terribly rare, these are fun pieces especially since this variety used the Barber reverse.
