I started recently in LF photography - I bought Super Graphic and already developed a few sheet films. As I needed more film holders I bought some on ebay and today it arrived. During the inspection I realized that some holders still contain film inside. I opened the remaining holders in the dark to check the presence of the film and five of them contains film sheets (10 sheets in total). Judging from the dark slide position one holder contains unexposed film, but other four appear to be exposed. I will probably try to shoot the unexposed film, although I am not sure what iso it is, how old it is or even if it is BW or color (I believe it is BW, because the one from the same batch I opened in the daylight is some kind of BW film). But what should I do with the exposed and undeveloped? Just throw it away or try to process? I am not even sure what kind of film it is. Some holders have some markings (C41-100, 80c, Dia 64) but the rest are without any notes. I do home development, both C41 and E6, so it is not a big deal for me to try to process it out of curiosity, but isn't it a waste of time - Dia 64 may well be Kodachrome and then E6 will just ruin it, and I have no clue what this 80s means. It could be that those notes are just wrong, leftovers from previous films, or it could be that the seller removed the dark slides and exposed film, but did not remove. And finally - is it even ethical to do that? What would you do?

Sheet film has a notched code on the side to identify the film type. Once you identify the film it should help with your decision. If it’s an easily processed sheet, try one and see.
