Help, please, with icons

[Alenka]

Dear forum users,

Help please with icons, any information would be useful, including the approximate market value. At first (Virgin), I can say the following, supposedly someone who once wore this icon to the museum for the assessment and there they were told that the icon was expensive and that, allegedly, was written this icon once in a century or something like that . Put my photo with a salary and without. I wonder if someone can see on the edge of the board something like stigma and poorly visible name. There are two hallmarks of salaries, one bottom and one on the rim of the Virgin.
Regarding the second icon, then all that I could learn, so this is just what is St. Nicholas Mozhajskij. If someone can tell about the time of creation, I would be grateful. In any case, thank you in advance for any information.
