Do these markings add any value to coins. I suspect it is a pigment issue during production but not sure it matters. Not even sure if it would be considered an error. Thanks Rich  *** Moved by Staff moved to a more appropriate forum. ***

Don't clean them off the coin. It will remove more of the coins surface lowering the grade even more.

The coin may have sat on some printed paper, or newspaper. Paper is not a good thing to have in contact with a coin. Especially BU/proof coins. Finger prints, sneeze droplets and paper alter BU coins. Think not? Put a proof coin in an envelope and leave it there for a while. They will turn dark.

Sadly, those marks probably detract from its value rather than adding to it.

Vertical stripes with a darker patina on the reverse of a coin are sometimes associated with storage in old coin folders. They were assembled by applying stripes of glue to backing paper before applying it to the cardboard folder, thus leaving a coin directly in contact with the glue on the backing paper.

Good point Biokimist. I bought an incomplete set of walkers in an old Whitman a few years ago for silver value and every single one had this streaking.

Quote: Looks like post mint staining to me. PMS .... on a coin, no less?  On a more serious note, along the lines of what Coop wrote, I've long made it a practice to store cleaned coins in oldtime paper coin envelopes that I've saved. Sometimes the results are pleasing, other times no difference. It occurs to me that perhaps, the OP's coin may have rested for some time on an old newspaper; hence, the lines.
