Hello PMG,

What does the "Toning" comment on the PMG certificate mean?

Kind regards,

[Jennifer F.]

Good morning,

Thank you for your message. The term toning is used on notes that have a brown tone to the paper in certain areas or it can be seen across the hole note.  Toning usually occurs from aging and/or when a note has not been properly stored over a long period. If the toning is severe, it can result in a NET grade. 

If you have any other questions, please let us know.  Thank you!
