Icon, help with the attribution and evaluation

[Gallida]

Hello!
These icons were ponovleny , suppose that in the 19th century. After the disclosure of the top layer were found images of Jesus and John the Baptist from the Deesis .
There is also an icon of the Virgin, but I think the value is not there, because after trying to open an earlier layer was not. Apparently, it was just to add in a number of later? Initially to clearing all the icons looked like this Virgin.
In all the icons on the back is scrawled signature.
