Variety Help - 100 Mon (Japan) Tempo Tsuho 1835-1870 Bronze coins

I would really appreciate it if someone could weigh in on the varieties pictured? I know one variety is quite a bit rarer than others. I'm not sure which one though. Clearly, the top right coin has a thinner rim, but other than that I cannot tell the difference. Any advice?

not sure ? all these look the same. KM#7 grade/value VG-$5.00 F-$8.00 VF-$12.00 XF-$17.50
I would take these to a coin show and ask the world coin dealers to look at them for you. also I would look on Ebay to see possible varieties for this coin/inspect pictures of current auctions and sold auctions
