I don't know much about US stamps but I looked these up in an Online catalog and it says these stamps were released in 1870.
The 1c Franklin with the 4 ring 2 does not look Canadian. I believe the font is not the same as the Canadian hammer. The 3c Washington does have the look of the Canadian strike to me.
Even though these 4 ring hammers were generally used 1857-1869 as previously mentioned, there were towns that used them into the 1870's.
Another interesting note is that the 4 ring 8 is from Chatham which is a town pretty close to Michigan state.
There are buyers who would buy the 3c Washington from you, including me.
Here's a 4 ring cancel on a Small Queen stamp from the early 1870's.
