So true...searching for rare stamps is an engaging challenge!
The Locomotive stamps in this collection may have been on letters received by the ancestor who began saving stamps in the 1800's, so I took a look at the others.
The cancel on the top stamp might be the same, although the more I look at it, the less sure I am. I'll check other stamps from the same time frame later.
Perhaps the ink blurred when the stamps were soaked off the envelopes (I wasn't the one who did that!).
