Starlyn, First we have to make sure you are talking about the right kind of photographic process. If it is flaking it sounds more like an ambrotype than a silver plated copper plate daguerreotype. A dag will reflect like a mirror and if it is unprotected it will wipe off since it is only a thin fumed on coat of mercury. The ambrotype is on glass and looks like a negative out of the preserver and case. The lacquers on the back will often flake, as well as, the emulsion at times. These collodian images on glass are fragile and will continue their loss with changes in temperature and humidity. The best bet is to create an environment that will be stable and where handling will be kept to a minimum. Create an acid free(nonbuffered) cardboard box or buy one exact to the size of the plate, limit too your wrap as it may cause flaking in opening and closing around the plate. Ambrotypes in good shape can be kept in small (to the size of the plate)acid free envelopes bought at archival supply houses but should be kept up right and in tight storage where plates will not fall or weigh down on one another. If this is an important document in the collection do call Eastman Kodak in Rochester or the Image Permanence Institute they will also help with the stabilization of such media.
