strategy Ukrainian domains selling strategy?

[Igor Mironyuk]

Ukraine is not popular country in the world that domains about Ukraine to be valuable and sold.
But I have some domains about Ukraine in .COM and .TODAY - SouthernUkraine.com, NikolaevPhotos.com (Nikolaev is the ukrainian city) Kherson.today (Kherson is the Ukrainian city).

NikolaevPhotos.com is more 3 years age, SouthernUkraine.com - more than 1 year and Kherson.today is almost 1 year.

I list them at various domain marketplaces, auctions, brokers and no success, no sales.

Help me with these domains selling strategy.
