Most valuable missing assassination relic

[Lincoln Wonk]

Betty and everyone
I know these aren't prime relics, but I'd love to know what happened to the screws larcenous Mose Sanford removed from the temporary coffin they used to transport President Lincoln from Petersen's to the Executive Mansion.
I also wonder what became of the strips of shirt Fred Petersen gave to his buddy William Ferguson on Saturday morning. In a later interview, Ferguson said he couldn't remember what he did with them.

Remember Ned Emerson's son found his trunk in the attic 60 years after the assassination, with a Ford's program, Ermerson's view of the assassination and some Booth pix inside. I wonder how many people carefully secreted away relics and their survivors didn't realize what they were and just tossed them.
