Help to determine the age and to evaluate the icon
 

Good time of day.
Parents have the old icon. It is known that when the great-grandmother died in the 1950s, said that the icon it had inherited from his grandfather. Unfortunately, photos are not of very good quality. Under the line of the inscription Nicholas the Wonderworker and the drilled hole (see hung on the wall).

The late 19th, early 20th century. Mass production, special values is not. If from the father, let him be your children.

Why the square cut out on the reverse side?

Apparently, bitches got. If you leave, there is shrinkage otherwise is because cut bitches and put in a "plug."

The photo, of course, bad... But, it seems to be printing, but not the painting

I agree. I'd add: it's not printing: painting/oil on Bezlepkina the Board.

Saw better, Yes, respect. Arkady, you are right: this painting.
But then, this is a pretty good painting and approval: "value is not" obviously wrong :)

Painting by iconic standards "so-so", the clothes are too simple, without complicated folds, fonts gospel also do not cause delight, to put it mildly..

The icon of St. Nicholas with 22 18 approximately 10 000 rubles should cost.IMHO

A bottle of vodka the same value. When he wrote is of no value meant that a liter of Chinese VS not such a great value.-
