Yuk... Why would someone do this? Unless they are a non collector who was given the sheet as a gift, but even still...
The question is store or show. Store: Place the currency in the tube it came in, if it is acid free. If not acid free paper tube, place the currency in a non PVC plastic tube. A tube will take up less room when storing. Now, if you want it mounted. Mount the currency on acid free paper in a picture frame, with acid free backing paper too. I hope this will help. Use non glare glass, and do not place the frame in full sun day light, the currency will fade.
