Clearly, both the seed packager and the vendor did not know the variety. If the seed looks like espresso-ground coffee, it is some variety of Nicotiana tabacum. If instead it looks like a coarser percolator-ground coffee, then it may be Nicotiana rustica. But it could be some other, utterly unsmokable species of Nicotiana.
Given their age, likely dubious storage, and their complete lack of provenance, I would only bother with them if you just like a challenge.
