No. 1 Bushū-Itō school, late Edo, depicting 3 oubergines (三茄子透 - mitsu nasubi sukashi). Often those tsuba have very faint inscriptions, so check thoroughly if a mei is present. No. 2 probably Meji or later, depicting a prunus branch (枝梅透 - eda ume sukashi); the supposed straw hat should be part of a branch with a blossom bud. Just my opinion. Bye, Mauro
