so the two tsuba are not from the same source.............
I have bought tsuba from Kunitaro ( the seller living in the land when boys have sticky fingers ) and so far not disappointed yet.
So the tachi tsuba is legit though not high quality but the second one is very very questionable.
If you are looking for an late Edo period tsuba and want it " cheap ", then anything less than 200 for this tachi tsuba is " reasonable " , meaning if you outgrow this later you can get your $ back.
