I have seen these 2nd day cancels and was not sure either. Thanks for asking the question, I would like to know the answer as well.
"...but it also lists Washington, DC on July 14 as a first day..."
No, they would not be considered as First Day Covers by any serious FDC collector.

I had gotten these covers at a show last month out of a quarter box! These are all second day cancels. Each of these covers had their first day in their home territory capital the day before, and these are all Washington DC cancels the following day.
I see that with Scott 795 "Ordinance of 1787", my ancient 2004 Scott's Specialized lists that one as having a July 13 first day in Marietta Ohio and New York City, but it also lists Washington, DC on July 14 as a first day. The ones I have posted above do not. Are these considered first day covers?
