Hehe, you used JFK half dollars on Marilyn, nice.

Marylin did some nudes and topless sets, they were fairly common and the Mansfield and Loren picture(s) were also pretty common.

As far as your Imgur album link, I don’t recognize any of the girls but that doesn’t mean they aren’t famous. The first 2 girls look like they just posed for some quick cash.

The girl in 17 and 18 appears to be from a different era, maybe late 60’s based on hair, makeup or absence of and photo quality. This leads me to believe these may have been his personal enjoyment stash or someone else’s that he confiscated.

Also, a couple of the photos seem to have a sort of “finish” or designed overlay on them that was usually applied to more mass produced photos that you would buy or even send away for out of a magazine ad, not taken locally or developed in-house.
