Need Id on these button teasers

[Buffalobackhoe]

I sifted these buttons several years back in a rag paper dump that closed down in the 1890's. I would guess that these one peice buttons date from around the 1860's or earler.? The large exploding shell button has a paris mark on back. the one with the lion has a mark that I cant make out.? My first thought is that they could be Canandian because I could not locate any of them in my copy of Alberts button or my 1955 Bannermans catalog.? Any help would be appriciated.?

Thanks for the look.
