There are certain stamps that collectors have zeroed in on to collect as a speciality. In the USA, such stamps are the 3c imperf 1851, the 3c 1869 Locomotive and the 2c 1883, all stamps that were issued to meet a first class rate and therefore were probably available from almost every contemporary post office. At the current time, I have about 250 different post office examples in my collection out of the 400+ post offices that were in operation in Vermont during the 1880s.
Here are a few highlights of what I was able to add to my collection. All are on full envelopes even though some of the scans show smaller versions.
An interesting killer from Chester.
