Type C reverse was used on all Philadelphia business strikes and primarily on the Denver issues. Breen reports that fewer than 0.1% of the Denver issues were produced with the type B reverse which makes them very scarce. As with the 1969 proofs, the type B reverse was used exclusively on the S-mint coinage.
