This coffin plate for Emanuel C Beam is without a date but we can tell from the style of plate and the frame it is displayed in that it dates from around 1880~1890. The photo was taken in Washington NJ so I went and had a look in the 1880 USA Census and found Emanuel living in Mansfield, Warren, New Jersey.
