After further research I am positive that the 1810 is an O-109 (R3). I was considering it for either O-109 or O-102, but the are in America is level with the E, something not seen on the O-102.
The 1826 is an O-108a, I couldn't see the die crack on the reverse until just now.
The 1828 I've narrowed it down to either the O-116 or the O-121. They have the same reverse, but only slightly different obverses. Since there are no die lines to the left of the date under the bust I am fairly confident it is an O-121.
