What to check on your 1999-S
- Make sure the mint mark really is an S. A worn or filled mark can be misread. It's what separates your coin from the 1999-P (8.9 million made).
- Judge the grade under good light. Check the hair above Kennedy's ear and the center of the eagle on the reverse.
Proofs from 1999 come with and without frosted devices. Coins with strong contrast are labeled Cameo or Deep Cameo and are worth more.
The story of the 1999-S
Eagle reverse and dwindling demand (1977 to 2001)
The eagle reverse returned in 1977. Halves saw little use in commerce and mintages fell into the tens of millions, then lower. The 1982 Philadelphia issue includes a variety missing Gasparro's FG initials from the reverse. In 1987 no halves were made for circulation; the 2,890,758 coins from each mint went only into uncirculated sets.
Silver proofs in 90 percent silver returned in 1992. A 1998-S matte finish silver half, 64,141 struck, was sold in a set honoring Robert F. Kennedy and is one of the scarcest modern Kennedys. Circulation strikes of this period often show bag marks from handling in large bags. Well-preserved examples of the low mintage dates, such as 1987, are worth seeking. The 1999 Philadelphia run of 8.9 million was also small.
Elsewhere in US coinage in 1999
The 50 State Quarters program began, with five new reverse designs each year in the order the states joined the Union.
How to recognize it
Gilroy Roberts' portrait shows John F. Kennedy facing left with LIBERTY above, IN GOD WE TRUST below and the date at the bottom. The reverse, by Frank Gasparro, is based on the Presidential seal: an eagle holding arrows and an olive branch surrounded by a ring of 50 stars. The mint mark was on the reverse in 1964 and has been below Kennedy's neck since 1968.
