Recorded use
Wiktionary exampleThese source excerpts show how IHC appears in context. They illustrate usage; the definition above remains the entry’s reference meaning.
I have an 1872 Indian Head Cent that appears to have either doubling in the lettering of AMERICA and several letters of UNITED STATES, or maybe it's been repunched. The coin grades a VG+, and although I have other IHC in my collection, most are G to Fair, so they don't have enough detail showing in the lettering.
