2016-S Shawnee, NIFC

The 2016-S Shawnee, NIFC opened the fifth year of San Francisco business-strike ATB production, the first of the year's five collector-only quarter releases. Susan Gamble's reverse renders the Camel Rock formation rising from the oak-hickory canopy of the Illinois national forest the design honors, the same composition carried on the Philadelphia and Denver circulation strikes. The Mint produced 1,093,510 pieces, the lowest 2016 NIFC figure and the smallest print run across the 2012-2016 range covered in this batch. The figure reflects the gradual decline in Mint Set sales as the NIFC line aged: 2012 ran 1.23M, 2013 inched up to 1.23M, 2014 dropped to 1.17M, 2015 recovered to 1.18M, and 2016 stepped down again to 1.09M.

Finish identification is the authentication question. The coin is a business strike with cartwheel luster across the fields, distinct from the 2016-S clad and silver proofs of the same design that share the S mintmark but carry mirrored fields and frosted devices. Mintmark position is identical across the three product categories, so the separator is field reflection: cartwheel rotation reads business strike, deep mirror reads proof. The clad composition (75% copper-nickel over a pure copper core, 5.67 grams, 24.26 mm) follows the standard Washington quarter formula since 1965, and counterfeit pressure on a sub-$10 modern Mint-direct product is essentially absent.

This is a Regular-classification issue with the slight scarcity edge that comes from the year's lower print run. Population reports at MS67 remain well-supplied despite the 1.09M figure, MS68 examples come up regularly, and pricing tracks the NIFC norm of modest premiums for raw examples and small step-ups at certified gem grades. The 2016 NIFC dates as a group trade marginally above the 2012-2015 baseline because of the reduced print figures, but the difference is too small to drive any tier-shift on the certified market. Set builders working through the 45-entry NIFC run pick the issue up from broken annual Uncirculated Coin Sets or dealer inventory at retail-floor pricing.
