I'm very "local" to Albany so I had no trouble digging a little deeper into one of the auction lots you highlighted in the current (6/6) E-Sylum.

Specifically, that would be Lot 178 in the June 2020 Stack's Bowers Francesca collection sale, the C.E. Horns Milk Depot c/s on an 1855-O US half-dollar.

The depot's address is still there, now located in the shadow of our busy Interstate 787, which runs about 15 miles north-south parallel to the Hudson River to connect Albany, Troy, and a few other localities to one another and to the New York State Thruway. I-787 is elevated at the point where 101 Green Street faces it...a real wall of concrete, access ramps, parking lots, alas.

Local real estate records show the current building has been at that address since 1830, so this is where that half-dollar originated... and where it was perhaps even actually counterstamped! As an aside, this address is located in a mainly residential neighborhood now called "The Pastures," only a few blocks from the mansions of the Schuylers (Alexander Hamilton's in-laws), Van Rensselaers, and other major historical figures from the pre-Revolutionary period forward.

Best to all the inmates at The E-Sylum, and wash your hands!
