From the Silver Swirls box
Copper penny is a Crayola crayon from Silver Swirls, a pack of 24 shiny colors that came out in 1990. The list of Crayola crayon colors says the codes for that pack are only estimates. A flat screen color can't show the metal shine, so #AD6F69 looks like a dusty brownish red. The ISCC-NBS system names it a grayish red.
Other metal crayons
Crayola's older copper crayon is lighter and more orange. A later metallic crayon, blast-off bronze, #A57164, comes very close to copper penny. Rose gold is a pinker cousin.
