Good to be back on Cointalk after a short break! I actually bought the gold and silver coins during the Olympics, and just received them today! Gold Meiji 2 BU-BAN-KIN, EDO (1868 - 1869), 3.08g. Silver Ansei 1 SHU-GIN Isshu Gin, EDO (1853 - 1865), 2g. Bronze 100 Mon "Tenpotsūhō", 1835-1870.
I love those little Japanese coins. I've bid on (and lost) several. That big 100 Mon though, that's super cool!
I've had multiples of all three types, but never at the same time. Your trio really looks good together!
