2 x 1 Mon? Old coinage from japan identification [Risolto]

Hello, I got the following coins ( japanese Mon's?) together with some other japanese coins.
Because my japanese skills are somekind of not existant I ask here for help from our experts .
The coins both have a diameter of circa 25mm and a weight of 3,7-3,9g.

Both 1 Mon "Kan'eitsūhō" (new type). The first one with mintmark 文C#1.2 - Kameido, the second is without mintmark

btw: the first line (which is without mintmark) on the first link (which is with mintmark) shall be deleted....

Thx for your help, those 2 look correct!
