Cabinet friction
Recently bought a lower grade 1824 quarter that's heavily toned except for the center of the reverse. I'm sure this piece is not an example of it but, it reminded me of the older auction catalogs that used that term in describing a certain lot. Would anyone have a picture of an old toned coin that was described as having cabinet friction? Thanks in advance. Dave

Might have had some type of adhesive that was subsequently removed.
Cabinet friction is generally hairlines on the high points due to rubbing against the "cabinet". It is generally unrelated to toning.

Agreed. And it’s also generally related to coins that are very close to mint state, as opposed to those that are worn to the extent of the one posted.

Agreed. Although literal cabinet friction probably also applies to circulated coins but no one calls it out as distinct from circulation wear.
