1964-D Tripled Die Obverse

The 1964-D Tripled Die Obverse sits one step further along the multi-impression scale than the better-known FS-101 Doubled Die Obverse, and it is correspondingly scarcer. A tripled die forms when the working hub strikes the die three times at slightly different alignments before hardening, leaving three offset images of the design elements rather than two. On this issue the triple impressions are most readable on IN GOD WE TRUST and on the date numerals, with secondary and tertiary outlines visible at 10x on the motto's center letters. The underlying coin is a Denver-mint 1964-D struck in 90% silver at 12.50 g (0.36169 oz of fine silver), and the 156,205,446 figure shown on the page is the combined 1964-D mintage covering all die marriages, not a separate count for the tripled-die variety itself, which represents only a small subset.

Attribution discipline carries more weight here than on the DDO. Raw "TDO" claims appear with some regularity on the secondary market, and the majority do not survive scrutiny because what sellers identify as a third impression is often machine doubling on top of an honest doubled die, not true tripling. The Wexler reference set (the Variety Coin Register maintained by John Wexler and Kevin Flynn) documents this issue, and PCGS recognizes the variety on holders with the appropriate designation. Diagnostics to look for under 10x: three clean, rounded letter outlines on the strongest IN GOD WE TRUST positions, and three offset digit forms on the date with no shelving or flatness suggesting machine doubling. Verification through PCGS or NGC certification is effectively required; without slab attribution, market acceptance is thin and the premium does not hold.

As a collecting target, the 1964-D Tripled Die Obverse is a specialist's piece rather than a generalist's. Circulated certified examples trade at a substantial premium over a base 1964-D, and Mint State examples in MS64 and higher climb sharply because the certified census across PCGS and NGC remains modest. The issue rewards patience and a willingness to wait for a properly attributed holder rather than chase raw cherrypick claims.
