Hello,
the second is a Japanese Kanei-Tsuho, 1-Mon. Tiger-Tail "Kan"
Very probably: Gembun Era, Kemeido-Sen.
Issue date 1737-1739; Edo-Kameido Mint, Musashi Province
Greetings from Germany
ps: all 4-Mon pieces have waves at the back. (japanese for waves: nami - therefore the Name: Nami-Sen for 4-Mon pices.)
