Fantastic finds Drew. Love the ornate suspender buckle as well. Origin of the wax seal (if that's what it is) gives me two ideas. Could the surname of the individual be Saturday? That is an uncommon but definitely real surname. Also, and less likely, could it be a mid-19th century 7th Day Adventist seal, signifying Saturday as the true holy day? Seems the date of your cellar hole pre-dates the creation of the Adventist movement in the 1850s or so, plus cheaper mail delivery from the civil war period onward generally led to a quick decline in use of wax seals. Regardless that's a great find. You've certainly been kicking some butt over the past week or so. Congrats.
