Paper Money

Displaying paper money requires using safe techniques

If you wish to display paper money, it is important that they be displayed in a manner that protects them from harmful environmental factors.

From time to time collectors ask how they can safely display their collection of paper notes. This month I will review this topic.

There are two major conservation concerns related to framing and exhibiting a paper note.

First, there is the issue of light. Exhibiting a paper note places it at risk from light damage. Light causes inks to fade and paper to degrade.

Second, inappropriate framing techniques and materials can also damage a note irreparably. I consider framing a paper note similar to framing a work of art on paper. The conservation concerns and techniques are similar.


Framed paper notes, like works of art on paper, should be glazed. The glass protects the paper from dust and pollutants in the air.

Some framers offer glass that is specially treated to screen out ultraviolet light. Readers will remember that UV is a very active portion of the light spectrum that can cause considerable damage. Choosing UV glass will protect against the UV component of the spectrum but not visible light. Visible light causes damage as well. So, be careful not to expose your notes to high levels of either natural or artificial light.


Framed works should always be mounted so that there is an air space between the glass and the note. The note should not be in direct contact with the glass. This is usually accomplished by placing a window mat around the work.

The choice of matboard can greatly affect the long-term health and wellbeing of a note. Choose an acid- and lignin-free matboard. Good-quality, acid-free matboard is now readily available at most framing stores at only a slightly higher price than acidic board.

If choosing a colored mat, make sure the matboard is colorfast. By colorfast I mean that the color will not “run” when the paper is wet. Noncolorfast matboard can stain a note if it gets wet.

Testing for colorfastness is straightforward. Ask your framer for a small scrap of the matboard you plan to use. Soak the matboard in warm soapy water and, when fully saturated, press it against a white paper towel. If no color transfers to the paper towel, then the matboard is colorfast. If there is a color transfer, then the matboard is not colorfast and should be avoided.

In addition to a front window mat you should also have a back matboard. The back matboard should also be good-quality, acid- and lignin-free and colorfast. The front and back mats should be taped together using a gummed linen tape. Acidic materials such as masking tape should be avoided.


How you mount the notes is important. The method you choose should be completely reversible and cause no long-term damage.

“Dry mounting” is not easily reversed without damaging the paper. Dry mounting is a technique that is best reserved for low-value works such as posters.

Works of art on paper are normally mounted by hinging them along the top of the paper to the back matboard using small Japanese paper hinges. The hinges are adhered to the work and the matboard using either wheat or rice starch paste. These pastes are strong, stable and completely reversible. A number of self-adhesive mounting tapes are available but should be avoided. When mounting a paper note, I prefer not to use hinges or any adhesive at all. Instead, I place the note in a Mylar pocket which is adhered to the backside of the window mat using 3Mtm 415 archival-quality self-adhesive tape. The note sits safely in the pocket and can be easily removed at any time.
