What means ?

Maybe in CCS it is less desirable for a bank cel because it is simply a different costume for each sequence. However, a valuable bank cel sequence would be for example, from a sailor mooon transformation or fight sequence. This scenes were not reanimated each time, they are the same cel sequence filmed once and used over and over.

I have a CCS Sakura Bank Cel (see my page for it) -but the number in the corner looks like A-9P, does anyone know what the 'p' means?
