[QUOTE="Conder101, post: 8024190, member: 66"]Same way you got cameos on the brilliant proofs from 1936 to 1972. After hardening and tempering, the dies would have an oxide layer on them. the dies would be cleaned in a acid bath to remove the oxide leaving a slightly etched surface. Then the dies would be polished. This polishing smoothed and polished the fields but did not get down into the devices. This results in a cameo contrast between the devices and the fields on the struck coins. But since that contrast is created by the very light surface etching in the devices, the movement of the metal during the striking rapidly "polishes" the surfaces inside the devices and the contrast disappears. The OP coin is not a cameo, it is not an SMS. It is an uncirculated coin struck from some severely worn dies showing heavy flowlining in the fields.[/QUOTE]
