All I can say is "wow". These are not normally found in
inherited or rummage sale collections.
I will start from the bottom stamp and work upwards.
The final stamp is a Scott 122, 90c Lincoln, from 1869. Catalogue value in VF condition is $2500.
Second from the bottom is a Scott #75 from 1862, 5c Jefferson, red brown, catalogue value $600
Third stamp from bottom is a Scott #76 from 1863, 5c Jefferson, Brown, catalogue value $150
The fourth stamp from the bottom appears to have a grill making it either (most likely) an 86 or 92 from 1868, and has a catalogue value of $575.
The 15c Lincoln stamp is either a 77, 91, or 98. Depends on whether or not it is grilled and what type of grill. Catalogue values vary.
Please handle these with care!
