Found some interesting things the other day at a house built in 1800- a few buttons, skeleton key, watch winder, late 1800s safety deposit tag, and a United Order of the Golden Cross medal (late 1800s secret society). This group would abstain from drinking in pursuit of living a prosperous life.
My favorite is the CW Staff Officers button which cleaned up nice. After doing some research I think it’s possible the owner of it was in the 10th MA Light Artillery from 1861-1865
