Edge device process differs on Enhanced Uncirculated Native American $1s

U.S. Mint employs different technology to impart edge inscriptions

All Enhanced Uncirculated 2015-W Native American dollars should have edge inscriptions that face right side up in relation to the obverse, U.S. Mint officials say.

That’s a departure from the Enhanced Uncirculated 2014-D coin, which can be found with the edge inscriptions facing either direction.

The differences between the 2014 and 2015 coins are the result of different equipment being used to impart the edge inscriptions at the Denver and West Point Mints.

The edge inscription on the 2015 coin is imparted during striking by a three-piece segmented edge collar. The edge inscriptions on the 2014 dollars, struck inside a plain collar, were formed post-striking on separate equipment. The Enhanced Uncirculated 2014-D Native American dollars can have the edge device appear right side up or upside down, depending on how the coins (in purely random orientation) entered the separate edge-lettering equipment, after having first been struck on a coinage press.

Both coins are exclusive to the 2014 and 2015 American $1 Coin and Currency sets.

Edge differences

Collector Brian Shields queried Coin World via email Sept. 4 concerning the edge devices for the Enhanced Uncirculated 2015-W Native American dollars.

After Coin World explained to Shields how the West Point Mint is executing the edge lettering on the 2015-W Native American dollars, he provided the following comments by email:

“This appears to be a change from last year’s set as the edge device was random and could be in Position A or B. I looked back at an article you published on 12/29/14 ... and it talked about the random edge lettering and that PCGS had certified several with both orientations (titled ‘Specimen 70 Enhanced Uncirculated 2014-D Native American Dollars sell for $750 each’).
