Because I'm not specialist in USA material, as recently in purchased collection, pop-up this two samples, searching internet around, see it also in Scott, but question stay if to go after Certificate (as I'm APS member, have this service available), or no fake are recorded on market?
Don't want to offer it for sale, and be surprised with something that I don't know.
I am not sure what your question is, but the top stamp appears to be a Scott #117 and the bottom one a Scott #119, type II. The 1869 set was issued with grills and were reissued in 1875 without grills. The main problem is the reissued fakes, where the grill has been pressed out and passed off as a reissue. If your stamps do not have a grill, then you might want to have them certified.
