I've seen other threads on the older Imperf and Perf series of stamps, but I have not quite found a similarly collated thread for sharing the 1861 series of perfs. I would like to start a thread as a result, and I have a few in my US album that I can start with.
Here are two Scott 63's, one with an 1862 cancel and a horizontal strip of 3 with a black 10 cancel on each individual stamp


I won't state I have any Scott 64's without more formal verification, but there are a nice range of hues among the various 3 cent washingtons. I selected a few with crisp cancels or interesting ones like STEAMBOAT.



There are two Scott 67's to show, both with red cancels.

The one Scott 68 I'll show is the one I'm trying to have as my profile pic, Abe Washinton that straddles the left plate on the top row (Position 10R).

The one Scott 69 Pair in the collection

I can't say 100% that this is a Scott 70 due to the difficulty in identifying 24 cent washingtons, but I like the red pinwheel cancel

The Scott 71 I will show also likely straddles the middle, this time from the right plate.

Finally, to wrap up the series, here are two Scott 72's I can show.
